[[caption-width-right:350:The lightsaber is the coolest weapon ever.\\
Search your feelings. You know it to be true.]]

->''"Your father's lightsaber. This is the weapon of a Jedi Knight. Not as clumsy or random as a blaster. An elegant weapon... for a more civilized age."''
-->-- '''Obi-Wan Kenobi''', ''Franchise/StarWars:'' ''Film/ANewHope''

The laser blade is a melee EnergyWeapon, with a cutting edge made of PureEnergy, giving it AbsurdCuttingPower. It also allows for a CleanCut the way a regular sword does not. Despite their AbsurdCuttingPower, {{sword fight}}s between two Laser Blade wielders [[ReconstructedTrope are still possible]] thanks to the fact that LikeCannotCutLike. Generally a type of ImpossiblyCoolWeapon, they require a lot of WillingSuspensionOfDisbelief, but are generally awesome enough to be worth it.

Laser blades exist purely because of the RuleOfCool. PowerGlows, therefore a weapon ''made'' out of glow must be ''really'' powerful. In real life, making such fancy swords is AwesomeButImpractical when FrickinLaserBeams [[NeverBringAKnifeToAGunFight decide war]], but then again, laser blade duels are frickin' awesome, and that's enough justification to be showed on-screen. Another possible in-universe justification in that the duelists are somehow ImmuneToBullets, whether thanks to DeflectorShields, The Force or any other such AppliedPhlebotinum, thus forcing the revival of old-school sword martial arts with laser blades.

Note that, although the most prolific TropeCodifier is the [[Franchise/StarWars lightsaber]], you'll almost never see the word "lightsaber" outside of that particular franchise for [[BlandNameProduct understandable legal reasons]]. Thus, such blades are given any variety of slightly less, but still awesome monikers, such as "beam saber", "energy sword", "plasma knife" and, for the [[JustForPun paronomasiacs]], "laser blade."[[note]]Because it sounds like "razor blade", get it?[[/note]] The energy blade concept tends to be OlderThanTheyThink; the TropeMaker is the "force knife" from the ''Literature/LuckyStarr'' novels written by Creator/IsaacAsimov under the pen-name Paul French in the [=1950s=].

Note also that the word "laser" is frequently used for fictitious energy weapons of all types, even in settings where the beams are created by AppliedPhlebotinum and don't share the real-world etymology of the word. Yes, despite having a perfectly fictional sounding, sci-fi/fantasy ring to it, the word "laser" is actually an acronym, standing for '''L'''ight '''A'''mplification through '''S'''timulated '''E'''mission of '''R'''adiation.

Despite being a sword made of energy, it's surprisingly rare to see one that can shoot a SwordBeam.

Sometimes, especially in video games, a laser blade may be mounted on a fighter ship. This version is even more of an ImpossiblyCoolWeapon than the usual melee variety.

A SubTrope of ElementalWeapon, LaserCutter, CoolSword, AbsurdCuttingPower, EnergyWeapon, HardLight, ImpossiblyCoolWeapon.

A SisterTrope to FlamingSword, HotBlade, RayGun.



* [[http://www.youtube.com/watch?v=fNf995B0_kU This]] Honda advert has a laser turkey carver.

[[folder:Anime & Manga]]
* ''Anime/MazingerZ'': In the ''Manga/NewMazinger'' spin-off, almost all mechas use lasers and light blades. ''Mazinger'' itself is the only one mecha that uses a regular, metal -albeit most probably that metal is {{Unobtainium}}- blade. SubvertedTrope because the mecha armors are laser-proof, [[KineticWeaponsAreJustBetter and thus Mazinger's metal sword is more effective than the laser blades]].
* Shana of ''LightNovel/ShakuganNoShana'' during a computer game. On a related note, she's usually a FlamingSword user.
* All the various energy blades in ''Anime/TenchiMuyo'', although many of these are semi-mystical in nature; the most powerful, the Light Hawk Sword, [[spoiler:comes from Tenchi's own God powers]]. Tenchi's regular sword, named Sword Tenchi (long story), actually serves as a master key to Juraian ships; its combat abilities are just a bonus. It also has the handy ability to throw up a ForceField. Ryoko, Washu, and Kagato have to ability to create energy swords outright, Ryoko's and Washu's being simple orange constructs, and Kagato's being green and more ornate, like a bastard sword. Lightsaber-like sound effects are standard when such swords are activated.
** In ''Anime/TenchiMuyoGXP'', energy swords almost identical to Star Wars lightsabers were implied to be both Galaxy Police standard equipment and carried by space pirates. They even had similar color coding - the Galaxy Police used blue laserblades and space pirates used red.
** In ''Anime/TenchiUniverse'', the BigBad [[spoiler:Kagato]] has a dark version of Tenchi's sword. It looks more like a large bastard sword in energy form than Tenchi's more Katana like blade.
** Subverted in ''Anime/TenchiInTokyo''. Tenchi's sword here is made of Crystals
** A few characters in the ''No Need for Tenchi''/''All-New Tenchi Muyo'' manga series swung around a few laser blades. The first villain sought to make a blade that was stronger than the Light Hawk Wing sword. Didn't work out for him. The last villain from ''No Need'' challenges Tenchi with two high-powered laser blades mounted on his hands. When he's forced to cut off a hand, the energy blade is so powerful in digs its way into the ground and causes his planet to go up.
* One arc of ''Manga/{{Gintama}}'' contains many StarWars references (like a character named Obi One Kenofi and arms dealers who look like [[http://www.tenmanga.com/chapter/Gintama405/285810/ Yoda as a bankrobber]]), so naturally, it features beam swords.
* ''Anime/{{Voltron}}'': Three words: Form Blazing Sword! Oddly enough, it was more or less solid. On the other hand, in the CGI-based {{Revival}}, "Stealth Voltron" is armed with an [[FunWithAcronyms N.R.G.]] Sword.
* ''Anime/PhantomQuestCorp'': Ayaka's signature weapon is her Star Sword, which she summons [[ImprobableWeaponUser by drawing her lipstick]] and invoking [[ByThePowerOfGreyskull its release command.]] Upon which, the tube elongates into a sword hilt, while the lipstick itself becomes a light sabre. It even makes the exact same sound effect upon activation.
* ''LightNovel/{{Slayers}}'':
** Gourry's AncestralWeapon, the Sword of Light, which at least has the advantage of being completely magical, allowing it to deflect, absorb, channel, amplify and emit incoming magical attacks. It's also capable of extending to nearly SwordBeam lengths. Lina used it to cast the [[DangerousForbiddenTechnique Giga Slave]] in a desperate attempt to destroy Shabranigdo.
** In ''Slayers Try'', sister weapons to the Swords of Light, including a [[DoubleWeapon spear]], bow, axe, and trident, all lasery. It also reveals them to be [[spoiler:dormant monster demigods from AnotherDimension, which {{Fanon}} holds to be the malevolent {{Living Ship}}s in ''Anime/LostUniverse'']].
** It is, however, possible for a mortal to create a lesser Laser Blade, as demonstrated by Pocota.
** All are activated by shouting the phrase "[[ByThePowerOfGreyskull Light, come forth!]]"
** Then there's the Psi-Blade in the sister series of ''LightNovel/{{Slayers}}'', ''Anime/LostUniverse''. They share the same method of empowerment, the mental willpower of the user. A particular episode also features a light-whip.
** Finally, there's Lina's "Ragna Blade" spell which creates a virtual blade capable of slicing through physical objects, and even reality itself into alternate dimensions. It's the only weapon or spell the monster race cannot avoid by ducking out of our reality.
*** …which, in an odd twist, is actually more of a ''dark''saber.
* ''Manga/{{Bleach}}''
** Pesche has Ultima. It's a sword whose blade is made of shining reishi giving it the appearance of a sword whose blade is made of light.
** Subverted with Uryū. The Seele Schneider is a Quincy weapon with a sword's edge. It's made of spirit particles (reishi) and therefore looks like a laser sword and functions as a VibroWeapon. Uryuu even compares it to a [[ChainsawGood chainsaw]]. However, while the Seele Schneider can be used in melee combat, it's actually an ''arrow''.
** When Ulquiorra releases, he can create green laser ''lances'' (called Luz la Luna) out of his reishi, which are just as durable as his normal sword. [[spoiler: When he uses his second form, the resulting lance (Lanza del Relámpago) can also serve as a FantasticNuke when thrown]].
** [[TheGunslinger Starrk]] normally uses twin pistols in his released state, though when the going gets tough, he trades those out for a [[DualWielding pair]] of blue laser swords.
* [[BloodKnight Ryuga's]] Ray Blade in ''Manga/{{Mahoromatic}}''. It uses a beam from a ''starship'' to power it up.
* ''LightNovel/SwordArtOnline'' has the Kagemitsu G4 in ''Gun Gale Online'', and is classified as a [[LawyerFriendlyCameo "Photon Sword"]], though it's mentioned by Sinon that it doesn't stop GGO players from calling them names like "[[WritingAroundTradeMarks Light Swords]]", or [[Franchise/{{Gundam}} Beam Sabres]][[note]]Nor does it stop RealLife fans of the series from flat out calling it those, or a [[Franchise/StarWars Lightsaber]]. In the anime, it even sounds extremely similar to how a Lightsaber does when swung or powered up or down. This is actually lampshaded when Sinon finishes listing every possible alternate name for the thing except calling it a lightsaber, and follows up by saying "It has another name, but I can't remember it."[[/note]]. This was considered a JokeWeapon in series since by the time anyone got close enough to someone to use it, they'd be riddled with bullets. Then Kirito gets his hands on one and, thanks to skills honed in two other VRMMO games that emphasized sword fighting, turns it into a LethalJokeWeapon, [[ParryingBullets deflecting bullets like a Jedi]]. After he leaves GGO, the Kagemitsu explodes in popularity as players try ([[DifficultButAwesome with limited success]]) to replicate his feats.
* ''Manga/MahouSenseiNegima'' has Evangeline emanating some sort of magic energy blade from her hand. She uses it once on the Headmaster (cutting his beard off so he won't interfere in the battle). Later, a weird psuedo-Eva created from a magic scroll and Negi's memories uses it to fight Negi.
** Negi can also do this, at least when he's fighting a BattleInTheCenterOfTheMind.
** While deliberately used to invoke this trope, the spell "Ensis Exsequens" is almost the exact opposite of a conventional Laser Blade; rather than pumping energy into its delineated region, it supposedly drains and isolates energy so as to cause the surroundings of every particle in its effect to become colder relative to it... for every particle [[LogicBomb simultaneously]], vaporizing the matter through sublimation. This incidentally produces intense cold in the blade's vicinity (fitting Eva's [[AnIcePerson theme]]). It's noted that since this spell [[NoConservationOfEnergy directly opposes the laws of thermodynamics]] (and logic), it's very difficult to cast; Negi's only learned an imperfect version of it.
* In the ''Franchise/{{Gundam}}'' meta series, laser blades, here commonly referred to as "beam sabers", are the common melee weapon used by heroes and villains both. Many series will start out with the heroes with a SuperPrototype armed with a state-of-the-art beam saber with the villains gaining their own near the end of the series. Continuations afterwards usually have both sides stick with beam weaponry from that point on. As the series goes on, melee beam weaponry take various forms, practical and impractical, from the high powered beam shields to beam axes to beam ''rotors''.
** Not all series deals with beam energy the same as the original. For instance, in ''Anime/MobileSuitGundam00'', early enemy Mobile Suits like the Union Flags used Sonic Blades, which were {{Vibroweapon}}s that can also turn into Plasma Swords. The Gundam Exia and its successors 00 and 00 Qan-T had special weapons that were actually solid blades that could be infused with GN Particles to make them as powerful as standard beam sabers.
** Averted in ''[[Anime/MobileSuitGundamIronBloodedOrphans Iron Blooded Orphans]]'', where everyone uses [[KineticWeaponsAreJustBetter physical weapons]] instead.
* Kuwabara in ''Manga/YuYuHakusho'' can summon an energy sword at will. It's not ''technically'' a laser sword since it's actually a manifestation of his spirit energy, but it functionally serves the same role.
* ''Manga/SgtFrog''
** In a parody of ''Franchise/MetalHeroes'', Space Detective Kogoro uses a laser '''''[[WoodenKatanasAreEvenBetter shinai]]'''''.
** Giroro is also seen using a beam sword during a ''Anime/MobileSuitGundam'' pastiche in episode 10.
* ''Franchise/DragonBall'':
** Vegito and Salza (from the Cooler movie) from ''Anime/DragonBallZ'' both create their own handheld Energy Blades.
** Goku Black and Zamasu from ''Anime/DragonBallSuper'' love doing this [[spoiler:due to being the same person.]] The former eventually expands it to an energy ''[[SinisterScythe scythe]]'', which [[spoiler: carves open nasty-looking rifts in space even when it misses.]]
** Later in the same arc, Future Trunks uses this technique to replace the broken half of his sword. It goes UpToEleven when [[spoiler: Goku, Vegeta and the surviving humans channel their energy into him, creating an ENORMOUS energy sword powerful enough to bisect Merged Zamasu.]]
** Kahseral of Universe 11's Pride Troopers can [[DualWielding dual-wield]] laser blades. Android 17 responds by ''catching'' one of them barehanded.
* In ''Anime/PhantomQuestCorp'', Ayaka's lipstick becomes her Star Sword whenever she unseals its power by [[ByThePowerOfGrayskull calling upon the Red Dragon's spirit to empower it.]]
-->'''Ayaka: (invocation)''' "Red Dragon spirit, capture Star Sword."
* The ''Franchise/{{Digimon}}'' franchise offers a few examples:
** [=MagnaAngemon=] of ''Anime/DigimonAdventure'' has one [[BladeBelowTheShoulder extending from his wrist]], named Excalibur. His evolved form Seraphimon can also form one in a similar manner.
** Justimon's Critical Arm in ''Anime/DigimonTamers''.
** Lobomon of ''Anime/DigimonFrontier'' dual-wields laser blades with his [[GratuitousGerman Licht Sieger]] technique. His later form, [=MagnaGarurumon=], also wields a laser blade stored in its chest compartment.
** Gallantmon X of ''Anime/DigimonXEvolution'', whose Victory Saber technique is a laser blade effectively [[{{BFS}} measured in miles]]!
** Susanoomon from ''Anime/DigimonFrontier'' takes the cake. What looks like a {{BFG}} creates a beam... that has a fixed length and becomes [[{{BFS}} suspiciously sword shaped]]. It bisects the ''entire core of the Digital World'' along with the opponent. [[CallingYourAttacks CELESTIAL BLADE!]]
* The knights in ''Anime/HeroicAge'' have laser bayonets that can be turned on and off.
* Cure Aqua of ''Anime/YesPrettyCure5'', of all people, gets one of these from her first MidSeasonUpgrade. Apparently Karen's a trendsetter, because when it came time for upgrades in the ''next'' season, ''everyone'' got laser swords.
* ''Manga/TheFiveStarStories'' uses its own version, known as a 'spadd': this is often paired with a regular sword, known as a 'speid'. Spadds and speids are used both by human-sized characters ''and'' by the giant robots they pilot.
* ''Anime/YuGiOhGX'' had the "Elemental Sword" card, which depending on your point of view, was either thankfully or unfortunately used only twice.
* ''UmiNoTriton'' featured a laser knife that was an heirloom of the Atlantis nobility. Yoshiyuki Tomino directed this in 1972 before Gundam and [[OlderThanTheyThink well before Star Wars.]]
* Amidamaru on ''Manga/ShamanKing'' gets awfully lightsaber-ish.
* ''Anime/SpaceRunawayIdeon'': The titular HumongousMecha has such weapon. The "Ideon Blade" is the absolute, indisputed heavyweight champion of this trope. ''It can cut one whole freaking planet in half'', and it is speculated that its reach is potentially infinite.
* Aleida & Takane Shishidou in ''Anime/TheGirlWhoLeaptThroughSpace'' use weapons called Tachyon Swords in battle (usually with each other).
* This is a specific ability granted to ''Manga/OnePiece'' admiral Kizaru thanks to his light-based Devil Fruit powers.
* Mina Hazuki of ''Anime/DarkerThanBlack'' can turn any object she touches into an energy weapon, be it bokken or wire or pebble.
* In ''Anime/{{Pokemon}}'', this is how the Oshawott family's SignatureMove Razor Shell attack looks like.
** When Lucario uses [[BadWithTheBone Bone Rush]] (formerly one of the Signature Moves of Cubone and Marowak), it manifests out of thin air and glows rather like a [[Franchise/StarWars lightsaber]]. And can be used in similar combat.
** The Swords of Justice's former signature moves (Before it was also given to Aegislash) Sacred Sword and in the case of Keldeo, Secret Sword, look like this.
* In ''Manga/ZettaiKarenChildren'', Tim uses his powers to make a Mecha that uses, among other weapons, a [[MundaneMadeAwesome Beam-Pick-Axe and Beam-Shovel]].
* Father Remington of ''Manga/ChronoCrusade'' has a giant laser blade {{BFS}} that he deploys from a crucifix.
* Several characters in ''Franchise/LyricalNanoha'' use variations of this.
** Fate is the most prominent user. She starts with an energy scythe in the [[Anime/MagicalGirlLyricalNanoha first season]], and later gains access to various kinds of {{Laser Blade}}s, from a BFS, to twin sabers, to a double-ended energy saber.
** ''Anime/MagicalGirlLyricalNanohaStrikers'' introduces Teana, who can switch her pistols into a pair of energy daggers.
** ''[=StrikerS=]'' also gives us the Combat Cyborg Deed and her Twin Blades, which are a pair of energy swords.
** ''Manga/MagicalGirlLyricalNanohaVivid'' has Victoria Dahlgrün, whose poleaxe could be split in two to reveal a hidden laser blade in its shaft.
* A laser saber is Bakumaru's main weapon in ''Anime/JuuniSenshiBakuretsuEtoRanger''. Interestingly, he didn't start the series with it; it was a souvenir he took from the [[FracturedFairyTale fractured Sci-Fi version]] of ''Literature/{{Momotaro}}''.
* In ''Anime/WorldConquestZvezdaPlot'', members of the White Light organization fight using glowing white energy swords, which are capable of shooting {{Sword Beam}}s.

[[folder:Comic Books]]
* In ''[[ComicBook/UsagiYojimbo Space Usagi]]'' "arcane" (ancient) [[KatanasAreBetter katanas]] can be adapted to "surge", allowing them to cut through metal and electrify opponents.
* After giving up the [[EvilWeapon Ebony Blade]], ComicBook/TheAvengers member the Black Knight designed and constructed a laser sword, often called his photonic or neural sword. The sword resembles a lightsaber in both its appearance and its effects on non-living matter, but it functions differently when used against living beings. Its "laser" blade is actually a neural disruptor; when the Black Knight cuts someone with it, it delivers a massive jolt to the being's central nervous system. This jolt is usually enough to incapacitate someone within just a few hits. Alternately, Whitman can reverse the sword's energy stream so that it encases its hilt and by extension Whitman's fist in a high-energy field. Using the sword in this fashion enables Whitman to punch with some unspecified degree of enhanced strength.
* Used by Prince Ethan [[spoiler: and later on, Prince Bron]] in ''Comicbook/{{Scion}}''.
* Comicbook/WarMachine typically has a laser blade built into his left gauntlet. Considering [[MoreDakka the trope this superhero usually follows]], it's rarely used.
* ''ComicBook/TwoThousandAD'':
** In ''ComicBook/JudgeDredd's'' universe, Hondo City (what was Japan) Judges in more recent years are issued with laser blades, replacing the traditional katanas from earlier stories. Other characters have used them as well. In fact, the first recorded incident of a "futsie" was when a man went berserk after his wife bought a laser carving knife and killed her with it.
** ''ComicBook/{{Shakara}}'': One of Shakara's most commonly used weapons is a glowing red laser blade [[BladeBelowTheShoulder attached to his arm]], which he'll occasionally [[DualWielding dual wield]].
* In Matt Wagner's ''ComicBook/{{Grendel}}: War Child'' series, Grendel-Prime uses a red laser sword.
* Rex and Kane, the two ''Tyrannosaurus rexes'' in ''ComicBook/JurassicStrikeForceFive'', frequently use their laser swords during major battles.
* ComicBook/{{Psylocke}}'s psychic knife looks like this.
* The knights in ''ComicBook/{{Camelot 3000}}'' wielded energy swords used for slashing, not thrusting, but still called them "raypiers".

[[folder:Fan Works]]
* ''Fanfic/ACrownOfStars'': The Rangers of Avalon Empire Army wield plasma-edged blades as part of their standard equipment.
* Kyon has one in the [[InMediasRes prologue]] of ''Fanfic/KyonBigDamnHero'' courtesy of a dead inter-dimensional robot out to kill them.
* ''Fanfic/TheLifeOfTheLegendaries'' has [[OlympusMons Palkia]] wield a [[StarWars lightsaber-esque]] sword. It is made from his psychic energy. In this continuity, Psycho Cut can manifest as this form as well.
* One of the five “Hitler Youth” in the New Zork chapter of ''FanFic/WithStringsAttached'' can generate a Laser Blade. The narrative promptly nicknames him Lightsaber Guy.
* Apparently in ''Fanfic/HarryPotterAndTheMethodsOfRationality'' there's something called "The Most Ancient Blade" that only those of a Noble/Ancient House can use. It is described very similar to a lightsaber.
* {{Manga/Naruto}} FanFic ''Fanfic/DreamingOfSunshine'' features The Sword of the Thunder God. It's similarity to a [[StarWars lightsaber]] is [[LampshadeHanging lampshaded]] by the main character.
-->''I was a ninja. I knew there were jutsu and weapons of every description and ability and more. And yet, some things were so deeply ingrained, like the cultural belief that the coolest weapon in the world was made of light and went zshooshm.''
* ''Legacy Of the Rasengan:Naruto'' : Naruto's Kaze Kiwa no Jutsu combines this trope (blade-shaped chakra) with RazorWind. Yes it is awesome. The length can be determined depending on how much chakra you pour in.
* In ''[[FanFic/SovereignGFCOrigins Origins]]'', a ''MassEffect''[=/=]''StarWars''[=/=]''VideoGame/{{Borderlands}}''[[spoiler:[=/=]''[=Halo=]'']] MassiveMultiplayerCrossover, lightsabers are extremely rare, but are often found in the hands of special agents from the Republic Intelligence Service. At one point, Kai Leng gets one and "The Lady" wields one along with her underlings. In ''FanFic/{{Frontier}}'' lightsabers become far more common, if only because the BigBad is mass-producing them for its troops.
* In the Australian FanFilm ''WebVideo/StarWarsDownunder'', the BigBad's stormtroopers have light-boomerangs.
* ''Fanfic/SonicBoomBeyondTheBlackHorizon'': This is one of the functions of the Enerbeam; in fact, it's the first one that Sonic figures out how to use. The shape and length of the blade varies by user; Sonic's has a decent range whilst Knuckles's is more or less a punching dagger. Lyric dual-wields a set of more traditional beam sabres.
* Creator/DetsniyOffSkiword seems fond of them, since two of his stories have used them so far. In Profesor Layton Vs Jack The Raper, we see Layton and [[TheGrimReaper The Grim]] [[FreudianSlip Raper]] have a fight using these. In Kid Icarus Uprising 2, the 16th chapter has Cloud Angle get a lightsaber [[EnemyMine from Hades]] in order to fight atop the Satellite Of Terror.
* In ''Fanfic/SonOfTheSannin'', Naruto receives from Jiraiya a modified kunai capable of projecting a blade of pure chakra, similar to Asuma's trench knives.
* In ''WebVideo/YuGiOhTheAbridgedSeries'', Yami Bakura and Yami Marik duel each other with Ancient Egyptian lightsabers (with "Through the Fire and Flames" by Music/DragonForce playing in the background) before switching to a children's card game.

* ''Franchise/StarWars'' is, as mentioned above, the codifier:
** A lightsaber is composed of a metal hilt that projects a three-foot colored beam of energy that serves as a blade. The energy is provided by a "kyber crystal" stored in the hilt. They can cut through virtually any physical substance, even thick metal bulkheads, but bounce off of each other to enable swordfights. George Lucas intended them to make Jedi more like a classic KnightErrant or samurai. Because they are close-range weapons and can be used to block and reflect blaster fire, they are supposed to be seen as defensive weapons, showing that Jedi use force only to protect themselves. This characterization is pretty much abandoned with Jedi of the Dark Side, who use lightsabers just as readily. Lucas sometimes calls them "laser swords" in interviews and in fact uses this term in the original script, this carries to the prequel where child Anakin explicitly called it a "laser sword" when he saw Qui-Gon for the first time and immediately recognized the latter as a Jedi Knight. Several characters also have their own take on the lightsaber:
** Darth Maul has a special hilt that can project a blade from either end.
** The [[WesternAnimation/StarWarsRebels Inquisitors]] use hilts that also project a blade from each end...''and'' they spin.
** [[WesternAnimation/StarWarsRebels Ezra Bridger]] built a lightsaber that doubles as a [[StunGuns stun blaster]]. [[spoiler:Until Darth Vader destroyed it.]]
** Count Dooku has a pistol grip for his lightsaber, enabling him to use fencing techniques.
** Kylo Ren has a lightsaber with two horizontal blades jutting from the hilt, like a crossguard. This design was a necessity due to Kylo Ren only having a cracked kyber crystal, the energy of which became unstable. He displays the ability to [[WeaponizedExhaust jab the crossguards]] into his foes in a BladeLock.
* One of these is wielded by a [[HumanAliens Human Alien]] named Akton in the ''Series/StarWars''-inspired {{Mockbuster}}, ''Film/{{Starcrash}}''.
* Being a sci-fi parody, ''Film/{{Spaceballs}}'' features an obligatory laser sword fight between Lone Starr and Dark Helmet, and the laser blades [[BladeLock get tangled]] at one point. "I hate it when my Schwartz gets twisted!"
* ''Film/HotShotsPartDeux'' features a random ''Star Wars'' parody when President Benson and Saddam Hussein suddenly whip out lightsabers during their climactic duel.
* In ''Film/TheHitchhikersGuideToTheGalaxy'', Trillian demonstrates the operation of a laser knife to Arthur, which [[MundaneUtility toasts bread as it's being cut.]] It also [[ShoutOut makes the lightsaber sounds.]] And miraculously doesn't cut the plate. DVDCommentary points out the FridgeLogic that the other side of the toasted slice will still be cold.
* In ''Film/ScottPilgrimVsTheWorld'', Gideon Graves uses a laser sword made of pixels, which is called the Digitana in the script.
* In ''Film/JayAndSilentBobStrikeBack'', their superhero identities Bluntman & Chronic use lightsabers. Bluntman's is called a "bluntsaber" and Chronic's is a double-bladed "bongsaber". Their archnemesis Cock-Knocker (played by Mark Hamill) uses a "cocksaber".
-->'''Chaka Luther King:''' I think George Lucas is gonna sue somebody!
* In Film/TheGamers: Dorkness Rising, Cass finds one which is a leftover from a previous, failed run of the adventure module, complete with an off-key music of a few notes from the Star War's theme.
-->'''[[RulesLawyer Cass]]:''' I see no lightsabre. That would be a copyright infringement. I see a psionic spiritblade.
** Which ends up biting Cass in the rear, when Lodge turns Cass's RulesLawyer way back around on him, by having the villain the party is facing stop it with a simple Dispell Psionic or similar spell. After all, Cass ''did'' say it was a [[ExactWords it was a psionic]], [[DidntThinkThisThrough magic weapon]].
* ''Film/TheReturn1980'' features an alien-tech bar of light that sometimes burns, sometimes cuts and cauterizes, and sometimes just acts like a normal knife.
* In ''Film/GodzillaVsDestoroyah'', Destoroyah's horn can sprout a laser blade powerful enough to injure Godzilla.
* In ''Film/TronLegacy'', Generated by the same Baton as Light Cycles, Light Katanas can be used by programs on the Grid, as demonstrated by Quorra during the fight scene in the End of Line club.

* Variable swords in Larry Niven's ''Literature/KnownSpace'' stories, which are simply stasis fields wrapped around monofilament wires. A notable subversion in that their power ''doesn't'' glow (the wires are nearly invisible, so it doesn't look like much of anything, and only the bright red ball on the end tells you where the sword point is), but they function a lot like energy swords.
* M. John Harrison's early Literature/{{Viriconium}} novel ''The Pastel City'', another pre-''StarWars'' work, contains energy swords called ''baan''. These have a thoughtful safety feature: the blade materializes around a solid core, which isn't necessary for the weapon to operate, but prevents the blade from activating improperly while it's pointing into the user's body.
** They also turn up in a couple of Harrison's later Viriconium stories, but in keeping with Harrison's deconstruction of SF and fantasy tropes turn out to be radioactive and have [[BodyHorror unpleasant effects]] on the wielder.
* Inquisitor Gregor Literature/{{Eisenhorn}} carries a pure energy power sword in the ''TabletopGame/{{Warhammer 40000}}'' novels ''Xenos'' and ''Malleus'', by Creator/DanAbnett. He regards it as much less crude than [[AncestralWeapon newer]] models, which are basically swords with a power field around them. [[spoiler:It still doesn't do him any good when he tries to cut an EldritchAbomination with it.]]
* The "force knife" in the ''Literature/LuckyStarr'' series, published starting in 1952, was the likely origin of the sci-fi version of this weapon. Technically, it's not a laser--it works the same way as a force field--but it's incredibly thin and can cut through anything, making it quite deadly. The hero's sidekick Bigman Jones carries one, and can wield it with great skill if needed.
* In Creator/JohnMeaney's ''Nulapeiron Sequence'' books (and the prequel, ''To Hold Infinity'' there may be found a device called a Lattice Blade. Apparently never used as a battlefield weapon, it is quite capable of slicing off a limb and being extended or contracted in size, yet remain pocketable when deactivated.
* Probably the UrExample, from [[Creator/IsaacAsimov Asimov's]] ''Literature/{{Foundation}}'' (That particular story was first published in 1944):
-->"...To put it simply, if I could sell a penknife with a force-field blade to a nobleman, it would be to his interest to force laws that would allow him to use it. Put that baldly, it sounds silly, but it is sound, psychologically. To make strategic sales, at strategic points, would be to create a pro-nucleics faction at court."
** More likely, it's from Creator/FritzLeiber's Gather Darkness (published in 1943), where the "rods of wrath" cause a lot of mayhem on bystanders when used in a duel:
-->"Like two ancient swordsmen, then, the warlock and the deacon dueled together. Their weapons were two endless blades of violet incandescence, but their tactics were those of sabreurs - feint, cut, parry, swift riposte."
* In the 1982 novel ''The Fires of Paratime'' by Creator/LEModesittJr, one character possesses an actual light saber; it's apparently the genuine article, having been acquired [[Franchise/StarWars "from some obscure group of galactic-wide do-gooders"]] during a trip to the distant past.
* Creator/StephenKing had the Wolves use these in the [[Literature/WolvesOfTheCalla fifth]] ''Franchise/TheDarkTower'' book.
* In Creator/MelisaMichaels' ''Skyrider'' series, when a belter picks a fight with Skyrider because she's trying to remain neutral in the Earth/Belt conflict, he ends up stabbing her with a "force blade".
* Mocked in ''Literature/TheWheelOfTime'', when one of the Chosen points out to the Dragon Reborn that his sword made entirely of fire is one the worst way to use his power that they can think of. Given that at one point the Dragon Reborn seriously considers ''snuffing out all of reality'', they were probably right.
** Either Moraine or Siuan did it as well using Air, to demonstrate how stupid doing it was. While she was going for a gender thing, it's still accurate: at least Rand knows how to ''use'' a sword, well enough to make it a practical way to express power, and isn't oathbound to never use such a weapon against non-Shadowspawn or to let somebody else use it.
* Creator/MCAHogarth's ''Literature/{{Paradox}}'' series has holoswords, which project a HardLight blade of variable length, width, and sharpness. They're primarily used for fencing, with an entire fighting style based around changing the blade settings in the middle of combat, but in ''Laisrathera'' Hirianthial uses one to great effectiveness in a series of [[DuelToTheDeath duels]].
* Another possible UrExample is Creator/ETAHoffmann's ''Master Flea'', first published in ''1822'', which features a duel between two sorcerers using ray emitting pocket telescopes. There are no rays visible, and it's not quite clear whether these are {{Laser Blade}}s or {{Ray Gun}}s, but the physical strain and use of "feints, parries, thrusts, in short, all the tricks of the fencing-school" strongly implies the former.
* As of ''Skin Game'', [[spoiler: Fidelacchius is now basically a light saber]]. What makes this even better is that the person wielding it [[spoiler: Butters]] is a Star Wars fan. And so, as it turns out, is [[spoiler: the Archangel Uriel]].
* An [[HilariousOuttake outtake]] at the back of ''Literature/FancyApartments'' has Carr playing with a lightsaber.
* In ''Wolfling'' (1969) by Creator/GordonRDickson the preferred weapon of High-Born (haughty, but highly advanced HumanAliens ruling an interstellar empire) are hand-sized "rods" that project an energy beam, length of which can be varied during fight.
* The Bloodswords of ''Literature/TheStarOfTheGuardians'' act a lot like lightsabers, but they can be switched to DeflectorShields at a thought. They also amp up their user's PsychicPowers. However, they have a nasty trick to them: anyone not of RoyalBlood who tries to use one gets cancer for their theft.
* There's multiple brands of electrified and glowing sword in ''Literature/LucifersStar'' as the weapons are used in a thriving dueling culture as well as being beneficial for breaking down personal shields. Commentary is made about the fact they're not actually that useful in real combat unless you're a complete lunatic (which is used to describe the main protagonist who ends up using them as often as his fusion pistol).

[[folder:Live-Action TV]]
* ''Series/{{Bibleman}}'' sports one of these, and the Star Wars influence is not subtle in the least.
* [[Series/SpaceSheriffGavan Every]] [[Series/SpaceSheriffSharivan Space]] [[Series/SpaceSheriffShaider Sheriff]] of Toei's ''Franchise/MetalHeroes'' franchise has a sword that can turn into one of these, appropriately called the [[TropeNamer Laser Blade]]. Each show has a {{Leitmotif}} whenever they use the weapon.
* In ''Series/TheNewAdventuresOfRobinHood'' when Marian is kidnapped to be a demon god's bride, Robin shows up with an Unicorn horn that can changed into different energy weapon's, one of which is a energy sword. This dissolves into a light saber duel when the lead worshiper, possessed by the god, reveals his own energy sword.
* In ''Series/{{Lexx}}'' [=S02E01=] Zev uses a light saber-like device, that looks more like a light saber with a handle of a chainsaw, to cut a dormant gigantic insect into tiny pieces. This device, like most of the devices in ''Lexx'', is not named.
* ''Series/KamenRiderBlackRX'' had one of these, the Revolcane as one of his attacks. The {{Macekre}}ed U.S. production referred to it as an "electro-saber" and had it shoot fireballs at the enemy instead of impaling them.
** ''Series/KamenRiderFaiz'''s bike handlebar sword takes on this appearance; it has no cutting edge as the damage comes from the energy in the blade.
* A few ''Franchise/PowerRangers'' and ''Franchise/SuperSentai'' weapons resemble lightsabers. Red isn't evil; it just means its wielder is TheHero. Blades generally glow when doing a FinishingMove, but are not energized all the time and have a metal rod (not sharp; it's the energy that does the damage) that can be seen beneath them. This goes for the aforementioned Faiz Edge and Revolcane/Electro Saber.
* In ''Series/VRTroopers,'' JB's sword can take on a lightsaber glow, and even extend into a ''laser-lance,'' with which he does most of his [[FinishingMove finishing]]. Sorry, [[StarWars Darth Maul]], you were beaten to the punch by quite a few years.
** Indeed, since ''VRT'' was adopted from the ''Metal Heroes'' series, this was a given; Ryan got his own Laser Blade in season 2 when they switched to ''Shaider'' footage. ''Series/{{Beetleborgs}}'', however, did not have any, oddly.
* ''{{Series/Warehouse 13}}'' has one of these in their ''{{Series/Eureka}}'' crossover, wielded by Fargo. It's a laser cutter from Eureka that was "modified" with Creator/BenjaminFranklin's ring from the Warehouse. That turns it into an actual lightsaber that even makes the appropriate sounds when moved. Fargo, being a HollywoodNerd, is in love with the improvised weapon.
* An episode of ''Series/EarthFinalConflict'' features an assassin using dual laser blades to assassinate people, while framing others using dreams. Notable for being of human design, as Taelons aren't big on swordfighting. Additionally, the blade can "extend" from either end, depending on which button is pushed, [[spoiler:which is how Liam kills the assassin]].
* The intro to ''Series/EvenStevens'' has Ren and Louis Stevens sitting in front of the TV, each with a remote control trying to change channel to what they want to watch. When they can't agree, they turn their remote controls into lightsabers and begin to battle one another in a display of sibling rivalry.
* In the ''Series/RedDwarf'' episode, ''The Inquisitor'', Kryten uses a laser [[ChainsawGood chainsaw]] to hack off the eponymous villain's hand to allow his past self and Lister to take the Inquisitor's time gauntlet. He is killed in the process, but thanks to Lister's later plan he gets better.
* ''Series/{{Defiance}}'' has charge-blades, typically the glowing blue blade is the size of a large scalpel (their original [[LaserCutter use]]), but at least once one was extended to shortsword length.
* The Shadows in ''Series/BabylonFive'' have a unique combat tactic where their large battleships send out an [[EnergyWeapon energy beam]] and slash other ships with it, instead of shooting them.
* ''Series/TheGoodies'': In "Snow White 2", Tim and Graeme have a duel with light sabers.

* Prominently featured in nearly all of the ''Pinball/StarWars'' pinballs, of course.
* All of the futuristic explorers in Creator/{{Atari}}'s ''Pinball/MiddleEarth'' pinball are armed with either Laser Blades or {{Ray Gun}}s. Makes sense, given that they're exploring a LostWorld filled with [[{{Kaiju}} giant dinosaurs]] and [[KillerGorilla monster apes]].

* ''Roleplay/DestroyTheGodmodder'': has had actual light sabers, as well as various other energy-type blades.

[[folder:Tabletop Games]]
* ''TabletopGame/{{GURPS}}'' has forceswords, and the Ultratech supplement even has a [[BladeOnAStick Laser Blade on a Stick]] that is [[StarWars "suitable for guards of the Galactic Emperor"]].
* ''TabletopGame/{{Warhammer 40000}}'':
** Power Weapons are a variety of conventional melee weapons (and some unconventional weapons) surrounded by a matter-disintegrating "power field" when activated, thus rendering them capable of tearing through most forms of armor. If the technical components are damaged or deactivated, they can be used as regular weapons.
** Their counterpart, force weapons, are also conventional melee weapons (''without'' unconventional weapons included) designed for use by psychics (or "psykers" in-universe). These weapons are powered by the psychic might of its user, punching through armor and dealing horrendous, lethal damage to anybody unfortunate to be on the business end of the weapon. These are nominally more powerful than most power weapons, they still confer the benefit of acting as regular melee weapons when deactivated, or in the hands of a non-psychic
** In one of the official army lists for a [[ArmyOfThievesAndWhores less-than-honest regiment]], a wargear option is stolen archeotech. This is a piece of strange and esoteric machinery that has a random effect from [[UselessUsefulNonCombatAbilities playing pretty tunes]] to [[WaveMotionGun blasting plasma at enemies]] - one of the results is stated as being a beam of coherent light that can be wielded as a sword and ignores armour.
** As mentioned above, the [[Literature/{{Eisenhorn}} Inquisitor Eisenhorn]] novels mention that Eisenhorn possessed a power sword without a physical blade for a time (essentially just a hilt until activated), emphasising how rare and precious it is. Indeed, in most of TheVerse, power weapons without a physical weapon to channel the power field are almost unheard of.
** The energy blade is statted in the TabletopGame/DarkHeresy splatbook Inquisitor's Handbook. It's very AwesomeButImpractical, as using it creates bright light and loud noise, making stealth impossible since it's really a beam of plasma energy. It also runs on plasma weapon canisters and can only be sustained for about a minute at the most.
* ''TabletopGame/{{Rifts}}'' has Cyber Knights and Mind Melters wielding Psi Swords, which they can create with their minds. Also the Lightblade, a MagiTek weapon.
* ''TabletopGame/DungeonsAndDragons''
** 1st edition had the Wand of Force; one of its powers was to create a 3-foot long luminescent shaft-shaped forcefield emanating from the wand itself that could be wielded as a + 5 longsword. DoesThisRemindYouOfAnything?
*** Later ''Mordenkainen's sword'' spell did something very close to this.
** And let's not forget ''brilliant energy'' weapons, which are often called "lightsabers" by the fandom. They're not quite the same, though: they simply ignore/pass through non-living matter without damaging it.
** Don't forget the Soulknife, a character class that can make an energy sword out of pure will!
** ''TabletopGame/ForgottenRealms'' spell ''chromatic blade'' creates a glowing in erratic colors, [[RazorFloss needle-thin]] line of HardLight. It can be blocked normally, but makes no sound, cuts as ''[[AbsurdlySharpBlade sword of sharpness]]'' and disrupts many "[[EverythingsBetterWithRainbows prismatic]]" spells.
** ''TabletopGame/{{Greyhawk}}'' spell ''Jaran's prismatic blade'' essentially is [[EverythingsBetterWithRainbows Prismatic Sphere]] in the form of a sword wielded by the caster. Inability to use spells with [[MagicalGesture somatic components]] while this thing is active is a small price for this grade of destruction.
** 5th Edition has the Sun Blade, a longsword hilt with a blade of [[LightEmUp pure light]] (that the wielder can cause to appear or disappear at will[[note]]like a lightsaber[[/note]]), which deals radiant damage instead of slashing damage, does extra damage to the undead, and can be [[MundaneUtility used as a torch]].
* In the TabletopGame/D20Modern sourcebook D20 Future, one available weapon is the Beam Sword, a "small metal handle generating a solid beam of plasma contained by a gravity induced forcefield."
* In the less known RPG "Ammo", laser swords are an excellent weapon with variable power settings. Sadly, the higher damage setting drains its energy reserve in a matter of seconds. Psi-blade are more powerful if held by fighters with high willpower, and less consuming.
* ''TabletopGame/{{Mekton}}'' has rules for not only a laser sword, but also a laser ''axe''.
** The add-on book Mekton Zeta Tech Manual allows for the construction of nearly any energy melee weapon you can imagine.
* ''TabletopGame/{{Exalted}}'' has beam weapons, made and most often used by the magitech Alechemicals.
** One of the characters on the cover of ''Manual of Exalted Power: Alchemicals'' even uses a "beamklave". What do you think it looks like in the art depicting it?
*** This gets even [[ShoutOut shoutier]] when Soulsteel caste Alchemicals typically have black armour and red beamklaves. Just add VaderBreath.
* Laser Knight from ''TabletopGame/{{Monsterpocalypse}}''
* TSR's ''TabletopGame/GammaWorld'' featured ''Force Swords'' that were force-fields shaped into a blade and could ''cut through anything except another force field'' (alongside a wide gamut of high-tech melee weapons, including vibro and [[http://en.wikipedia.org/wiki/Monomolecular_wire monofilament]] blades). Since the first release was in 1978, it's debatable how these weapons correlated with the introduction of Lightsabers in the original ''StarWars''.
* ''TabletopGame/{{Paranoia}}'' has force swords, explained as monofilament fiber inside a force field. Too bad they're only available at Blue clearance. [[CrapsackWorld This being Alpha Complex]], the force field periodically fails, putting the wielder at risk of cutting himself as the fiber whips around loose.
* TabletopGame/{{Shadowrun}} has the Centurion Laser Axe, although it's never made quite clear how the laser beam follows the arced blade... All the rules state is that it can lose it's focus when hitting hard materials like heavy armor.
* TabletopGame/SentinelsOfTheMultiverse has Gene-Bound Ion-Lancer and L'Epeiste, minions who work for Grand Warlord Voss and La Capitan respectively, each wield one. Ion-Lancer's grants him immunity to energy damage and damages the hero with the least HP, while L'Epeiste's lets him deal damage to the healthiest hero equal to the number of Equipments and ongoings the heroes have.
* ''TabletopGame/{{Dragonstar}}'' has Sunswords, sacred plasma swords that use divine magic to channel the power of suns.
* The closest thing ''TabletopGame/MyriadSong'' has to the traditional "lightsaber" is the Xenharmonic Blade, commonly carried by Remanence Aristocrats and [[AbusivePrecursors Syndic]] LostTechnology. [[LaserCutter Laser torches]] can also be used as improvised weapons like many other power tools. Meanwhile Ghibli blades consist of a "hilt" resembling a small jet engine and project a "blade" of superheated air.
* The Ray Sword from ''TabletopGame/RocketAge'', essentially a lightsaber made up energy contained by the same kind of technology as RAY shielding.
* As befitting an Archetype referencing ''Franchise/StarWars'' in the ''TabletopGame/YuGiOh TCG'', Kozmo Farmgirl, Kozmo Goodwitch and Kozmoll Wickedwitch use 'lightswords', which are lightsabers in all but name.
** Now in the form of its own equip spell card, Kozmo Lightsword.
* The Jedi-inspired Just Blade track for Sages in ''TabletopGame/LegendSystem'' lets you create one with your mind as its first circle ability.
* In ''TabletopGame/EclipsePhase'' a "plasma blade" looks vaguely like a blunt sword but has plasma nozzles along one edge.

[[folder:Video Games]]
* ''VideoGame/ArmoredCore'' has [[ExactlyWhatItSaysOnTheTin Laser Blade]] attached on the AC as melee weapons, either conjoined with the forearm (Nine-Ball and other first generation AC) or as standalone parts (late generation AC). Unlike most examples, the blades are typically not solid, making them less useful for dueling and more useful for destroying stationary targets or as an EmergencyWeapon in case the user's ranged weapons run out of ammo, though [[DifficultButAwesome dedicated blade-builds]] ebb and flow in popularity and effectiveness throughout the series. The PlayerCharacter always [[StarterEquipment starts off with a laser blade,]] and two of the most prominent laserblades are the Moonlight, a heavy LB [[InfinityPlusOneSword with insane stats]] and a ShoutOut to [[Creator/FromSoftware From Software's]] other games (see below), and the Toros, a shield that had two Laserblades and was known as [[BigBad Stinger's]] weapon of choice in one of the games.
* In ''VideoGame/StarCraft'', Protoss Zealots wield PsychicPower-fueled energy swords called "Psi Blades". Dark Templar wield more powerful blades, but with a different power source, called "Warp Blades". They are even color-coded, similar to lightsabers; the standard Khalai[=/=]Daelaam Protoss use blue blades, the Nerazim (the Dark Templars' sect) use Void-powered green blades, while - as revealed in ''Legacy of the Void'' - the very Sith-like Tal'darim have red blades. While most Protoss have to use arm-mounted projectors with built-in amplification crystals to create and project their blades, ExpandedUniverse novels imply that especially-powerful Protoss like Tassadar can create those at will without the use of amplifiers. [[spoiler:[[TheDragon Narud]] also displays the ability to form a crimson psi-blade without an emitter]].
* ''VideoGame/DungeonFighterOnline'' has these as an exclusive type of sword for Blade/weapon Masters and Vagabonds (not yet in any NA build), with a few other weapons having a beam type. While not as powerful as other examples, it's the fastest weapon they can use by far and the 'shock' damage they can inflict will add armor ignoring damage to combos (making them usefu for enemies with MetalSlime level defenses)
* Zero's Z-Saber in the ''VideoGame/MegaManX'' series, which, in addition to being friggin' cool, also had the ability to change shape, length, and ''power'' as the situation required. Not to mention ''elements''. He can turn it into a flaming sword of death (which makes sense, sort of) or into a sword made entirely of ''ice'' (which just breaks several laws of physics). ''X8'' grants him laser [[PaperFanOfDoom harisen]], a laser glaive, and a laser ''hammer and knuckle dusters''.
** X would later receive this Z-Saber in X6, with Zero getting a new one that's literally exactly like the ones from Star Wars. He can still imbue it with elements however.
** In X5 and X6 there is Dynamo who has a variable length dual ended Laser sword.
** In the ''VideoGame/MegaManZero'' series, there's Harpuia (who uses TWO), Omega, and Elpizo, who all use their own laser swords. In ''addition'', Zero also gets a laser spear, laser shield, a laser ''grappling hook'' (made from the remains of the laser spear), and ''laser tonfa''.
** In the original ''VideoGame/MegaManX'', Sigma used his own saber during his first boss phase, which looked almost ''exactly'' like the Z-Saber despite predating it, as Zero himself didn't use the Z-Saber in that game. This prompted a few EpilepticTrees over whether or not it's the same sword.
** In the ''VideoGame/MegaManBattleNetwork'' games, most of the swords appear to be of this nature. Protoman and Colonel both [[BladeBelowTheShoulder have one as an arm]].
* The Energy Sword from the ''Franchise/{{Halo}}'' series. According to the fluff, it's actually a envelope of plasma that's held in shape by electromagnetic fields. It's good for both dueling and assassinations, since the blades turn invisible along with the [[InvisibilityCloak active-camo]] used by Elites.
** ''VideoGame/HaloReach'' shows that some Elites, in addition to their plasma swords, wield wrist-mounted plasma daggers.
* ''VideoGame/SystemShock'' and its sequel have the Laser Rapier, replete with "glowing" animation and constant droning noise (which gets irritating pretty quickly), but it has neither the power, the brightness, the sparks or the cut-everything-to-bits destructive capability of lightsabers. From the in-game description: ''The unit works by projecting a porous field of reflective material in a shaft shaped region around the base of the rapier. When the material is bent (as when the rapier strikes a target) the intense refracted light inside is released locally, causing intense burns to the target.'' Of course, the attack animation doesn't display this alleged local release of burning light which, surprisingly consistent with actual lasers, damages mechanical enemies more than biological ones. ''VideoGame/SystemShock2'' also has the Cerebro-Energetic Extension psi power that temporarily generates a semi-transparent psi sword for you to use.
** It's not technically a laser blade in the first, but just an AbsurdlySharpBlade: ''This energized lance projects a monofilament thread that is suspended in a contained energy field. Upon contact, the thread slices through organic and synthetic materials, permanently disabling most creatures and robots.''
** In the first, there wasn't much point to using anything ''else'' once you got it - so long as your batteries didn't run out, it'd happily chop through organics or robots alike, and when combined with the rollerskates turned you into a near-invincible juggernaut. It's nerfed significantly in the sequel, though: Not only does it do less damage,[[ActionBomb but it specializes in killing enemies that explode upon death]], with predictable results.
* The Beam Sword in the ''VideoGame/SuperSmashBros'' series. In the first game it had a definite length, while in ''Melee'' it starts off short but extends when used to land strong attacks. And in the Japanese version, it actually used lightsaber sound effects. (In ''Brawl'', the lightsaber sound effects came overseas as well.) ''Melee'' and ''Brawl'' also had the blade automatically scale to suit the wielder's size.
** Some [[VirtualPaperDoll Mii Fighter costumes]] for Swordfighters also feature energy swords as part of their costume.
* In the ''Franchise/ShiningSeries'', the [[VideoGame/ShiningForce first game]]'s plot involved the main character wielding a Laser Blade that was made of Light Energy and another one that was made of ''Dark'' Energies. The "Chaosbreaker" obtained later in the game (renamed the "Force Sword" in the series' later installments) is made of ''both'' of these energies. All three swords are obtained through the normal playthrough and are all considered [[SwordOfPlotAdvancement Swords Of Plot Advancement]] ''and'' [[InfinityPlusOneSword Infinity Plus One Swords]] to boot! [[spoiler:(But you lose the Light and Dark swords in order get the Chaosbreaker.)]]
* Travis' Beam Katana in ''VideoGame/NoMoreHeroes'' actually handles this in a sensible and relatively realistic manner. The hilt extends a "cap" to terminate the beam, and the beam is projected along a central filament strung between the hilt and the cap. The downside is that this makes the Beam Katana look like nothing so much as a Fluorescent Light-bulb Of Death. Then again, given the game's sense of humor, [[RuleOfFunny this was probably intentional.]]
** Then again, he can upgrade to a ''five''-bladed version of the Beam Katana, which looks less like a sword than a large laser club...
** Then again ''again,'' his ultimate weapon plays this trope straight. It is, quite literally, a beam ''katana'', [[spoiler:fashioned after the weapon of his recently deceased master]].
** And when you consider the sequel and the other characters in both games, there's a beam lance, beam zanbatou, beam nodachi, beam ''giant briefcase that transforms into a katana/ludicrously oversized straight-razor"...
* ''VideoGame/Kirby64TheCrystalShards'' has Darth Maul-esque double-bladed lightsabers with Cutter+ Spark. A tap of the button kills everything around Kirby, and enemies die just by walking into the blade. Yes, it's badass as it sounds.
* In ''VideoGame/TheGuardianLegend'', the eponymous Guardian's Saber Laser (single blade) and Cutter Laser (dual blade) sub-weapons deal lots of damage to enemies at close range. When she's in ship mode, they're not quite as effective.
* In ''VideoGame/TalesOfPhantasia'', by hunting a little in the sunken city of Thor, you can get Laser Blades for Cless to wield. If you happen to pick up extras, they sell for quite a price back in MedievalStasis land. And if you're too lazy to hunt for them, they're storebought a bit later on.
** You find it (and a Laser ''Shield'') as a weapon for Zelos in ''VideoGame/TalesOfSymphonia'' as well.
*** Kratos can wield that as well. And if you do have him rejoin you, he comes already equipped with one, rather than his flashy [[RuleOfCool Flamberge]]. Unfortunately, he comes for a boss fight, and the laser blade is light elemental. [[LightIsNotGood Guess what the boss's Element is.]]
* ''VideoGame/DeusEx'' has the Dragon's Tooth. While visually resembling a Laser Blade, it is in fact an AbsurdlySharpBlade constantly maintained by a nanite cloud. The blue glow is a side effect of the nanites, which the sword shares with all other nanite-based items (Paul's and [=JC's=] eyes, upgrade canisters, augmentation canisters...).
* ''VideoGame/MakaiKingdom'' has laser blades as a weapon class. They are noticeable for having the highest base attack of all the melee weapons bar none, and are really good against vehicles as well. However, none of the base classes you gain prior to a NewGamePlus can proficiently use them.
* ''Franchise/KingdomHearts'':
** [[VideoGame/FinalFantasyVIII Squall]] / Leon can form one of these out of his Gunblade as a reference to his "Blasting Zone" finisher in his original game.
** Xemnas [[DualWielding Dual Wields]] blades of PureEnergy that manifest from his hands. He can also fire them like projectiles. In ''VideoGame/KingdomHearts358DaysOver2'', his signature weapon is the "Interdiction" and the other types of Etheral Blades he wields [[http://www.khwiki.net/Weapons_of_Organization_XIII#Xemnas.27s_Ethereal_Blades are given more variety,]] with various shapes and colors and some appearing as blades of energy projected from a central core instead of being entirely energy. Except for his JokeWeapon, a pair of fans.
** The Unknown, aka [[spoiler:Young Xehanort]], of ''Birth By Sleep'' and ''Dream Drop Distance'' dual-wields a pair of blue Laser Blades. The Keyblade associated with him, No Name, is essentially a Laser Blade Keyblade.
** In ''VideoGame/KingdomHeartsBirthBySleep'', Terra and Aqua share a Command Style called Bladecharge that forms one of these around their Keyblade. In ''Dream Drop Distance'', Riku has this power as a Link Style.
* In ''VideoGame/DisgaeaHourOfDarkness'' you'll occasionally come across enemies wielding a 'Light Saber' which looks exactly like a Star Wars lightsaber. These can be stolen, and if found as legendary quality weapons can become quite decent [[InfinityPlusOneSword Infinity Plus One weapons]] if levelled properly.
** The flavor text on them even has a bit of a ShoutOut-- "The force may be with you..."
** The actual InfinityPlusOneSword, the Yoshitsuna, has the appearance of a laser blade.
** There are other laser weapons in ''VideoGame/{{Disgaea 2|Cursed Memories}}''. There are even laser spears and laser axes.
* ''VideoGame/DeadRising'', which takes place in a shopping mall, has several toy laser swords you can loot from a toy shop. They do terrible damage, at least in the original as compared to the powerful but fragile ones in ''Chop Till You Drop'', but the fact they make you emit a glow when wielded (and, strangely, when held in your inventory) basically make them the game's torches. There's also a special unlockable Real Laser Sword, but its durability means you can't use it long.
** In ''VideoGame/DeadRising2'', Chuck can make Laser Swords by combining a flashlight with some gems. It gets more lethal when he [[SawItInAMovieOnce sees it on a movie poster]].
* ''VideoGame/FinalFantasyVI'''s Ultima Weapon may qualify for this trope. It sure ''looks'' like a lightsaber, and even [[DoesThisRemindYouOfAnything extends in length depending on the damage dealt]]. If it does less than 500 HP of damage, it looks smaller than a dagger. If it does over 1001 HP of damage, it becomes longer than the character's sprite is ''tall''.
* ''[[Franchise/SaGaRPG Final Fantasy Legend]]'' has a weapon called an "L-saber". The Japanese version straight up calls it a "lightsaber", and the ones featured in the Nintendo DS remake of ''[[VideoGame/SaGa2 Legend II]]'' looks exactly like, well...
* ''Franchise/FinalFantasy'' loves this trope like they love {{Shout Out}}s to ''Franchise/StarWars''. In addition to the aforementioned weapons, there are elemental weapons. Moreover, there's a "Light Saber" in ''VideoGame/FinalFantasyTacticsAdvance''.
* [[http://www.youtube.com/watch?v=BVjJkYyMbLA&t=1m45s One weapon]] in ''VideoGame/SuperRobotWars'' is an enormous laser sword that makes no effort to stop its blade. The bloody thing is visible from space.
* In ''VideoGame/GunstarHeroes'', the lightning + fire combo creates a gun that shoots a laser that terminates after a short distance. This pseudo laser sword is one of the best combos in the game because it can deal out a lot of damage and cancel out most enemy shots.
* ''VideoGame/RadiantSilvergun'' has the Radiant Sword, an energy sword wielded by a ''space fighter''.
* From ''VideoGame/EscapeVelocity: Nova'' comes the ever-popular Thunderhead Lance - essentially a giant beam of damage sticking out the front of your ship. Makes absolutely ''no'' sense, but when your [[RuleofCool end result]] is [[RuleofFun space jousting]], how could you not?
* ''VideoGame/{{Einhander}}'' has a laser blade weapon pod. The Einhander is a space fighter with a grappling arm specifically built to use enemies guns as it finds them. Enemies using a laser blade do not have a grappling arm. They just have a laser sword sticking out of a hardpoint in their front that may be pointed at you. It is the most beautifully nonsensical thing in the game, especially since doing a fireball motion while activating it will cause it to lance forward about three times its original length for a moment.
* The original ''VideoGame/JetsNGuns'' has the Tsunami Generator which, when fully upgraded, resembles a laser [[Franchise/StarTrek bat'leth]]. The ''Gold Edition'' adds the Tsunami Beta, which resembles a ''spinning'' laser bat'leth. They're also amazingly powerful, and (somewhat realistically) create a huge amount of waste heat.
* The ''VideoGame/NeverwinterNights'' Community ExpansionPack includes alternate blade appearances for weapons from daggers to rapiers to two-bladed swords that look remarkably like lightsabers. They don't actually change the in-game effect, however.
** The ''[[VideoGame/D20ModernNeverwinterNights d20 Modern Mod]]'' completely alters the kukris to replace by ''Star Wars''-style lightsabers.
* In ''VideoGame/CommandAndConquerRedAlert3'', Imperial Warriors are armed with [[KatanasAreJustBetter beam katanas]] that they use for banzai charges to instantly kill infantry.
** AllThereInTheManual: They're actually superheated regular katanas.
* In ''VideoGame/SilentHill3''[='s=] NewGamePlus, one of the potential bonus weapons is a "beam saber." Given that the game is possibly the darkest (both figuratively and literally) of the series, and that the main character is both the youngest of the series' protagonists and the only female among them, the game can feel extremely oppressive. So it's a bit of a MoodWhiplash (though not necessarily in a bad way) when you gain the ability to turn Heather into the MagicalGirl "Princess Heart" (complete with TransformationSequence and appropriate costume), and either fight with a lightsabre or ''[[NinjaPirateZombieRobot shoot laser beams]] from your freaking [[EyeBeams eyes]]''.
** MagicalGirl, or girl-sized SuperRobot?
* ''VideoGame/MortalKombatDeadlyAlliance'' has Cyrax with the "Pulse Blade".
** Before that, in ''VideoGame/MortalKombat4'', Cyrax had an earlier model of his Pulse Blade called the [[StarWars "Sabre of Light"]]. [[SarcasmMode Subtle]]. [[YouWannaGetSued Very]] [[LawyerFriendlyCameo subtle]].
** ''VideoGame/MortalKombatArmageddon'' gives Sektor [[DualWielding dual]] red-color pulse swords. Obvious hinting at his evilness.
** ''VideoGame/MortalKombatX'' gives Takeda [[DualWielding a pair of pulse blades]] in his Ronin variation.
* Hwang in ''[[VideoGame/SoulSeries Soul Edge]]'' has two "light-edged" swords in his repertoire, one whose blade is transparent and his [[InfinityPlusOneSword Ultimate weapon]], whose [[{{BFS}} very long edge]] is only visible when swung. These were later inherited by his pseudo-MovesetClone Yun-seong since ''Soulcalibur II''.
** Funny how two Sith and a Jedi finally jump in and shows everybody how it's really done in ''Soulcalibur IV''.
* Coinciding with his full transformation into a {{Cyborg}} since ''VideoGame/{{Tekken}} 3'', Yoshimitsu's katana has been shown as glowing like a lightsaber. Official art and [[AllThereInTheManual material]] explains it's just the evil energy stored in it that does the trick, thought.
* ''VideoGame/RatchetAndClankUpYourArsenal'' has a cheat code that replaces your wrench with a double-sided one of these.
* Space Pirates in ''VideoGame/MetroidPrime'' use energy blades as melee weapons. In the sequel they only had metal blades (although they were called "photonic scythes", so they may have been a 40k-style "power field" involved), except for the Pirate Commandoes, who carried a gun that could fire energy projectiles or large exploding balls of every, as well as project a short beam blade.
** Elite Pirates have energy claws.
* ''VideoGame/StarOcean1'' gave you light sabers called "Force Sword" (with a graphic nearly identical to the ''Star Wars'' version) as part of the plot; they were the only weapons that could harm the BigBad.
* Taking place in the future, several ''VideoGame/PhantasyStar'' weapons are comprised of lasers, or "photons", in the ''Online''/''Universe'' games. Armor, as well; one wonders why they didn't outright ''call'' it a force field, but [[{{Fanservice}} we know the real reason.]]
** And just like ''VideoGame/MegaManZero'', they liberally apply these lasers to ''any'' sort of weapon. Laser boomerangs. Laser whips. Laser ''fists''. Laser ''[[SerialEscalation grenade launchers.]]''
* The Sword of Moonlight is a recurring item in Creator/FromSoftware games. It appears under various names in the ''Videogame/KingsField'' games, ''Videogame/DemonsSouls'', ''Videogame/DarkSouls'' and [[Videogame/DarkSoulsII its sequel]], and the Old Hunters DLC for ''VideoGame/{{Bloodborne}}''. The sword has a tiny physical blade that projects a larger, magical blade made of moonlight. Usually, only the latter is usable, however its appearance in ''VideoGame/{{Bloodborne}}'' departs from the norm by enlarging the physical blade and allowing it to be used as either a typical sword or Laser Blade.
* ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' has the Guardian and Ancient Weapons, which are made of HardLight and include arrows, swords, axes, spears, and even [[ChainsawGood chainsaws]].
* You can replace your stick with one of these in ''VideoGame/{{Ico}}'''s NewGamePlus [[BraggingRightsReward for no real reason]]. [[BadExportForYou But only in the Japanese and European versions]].
** This is only if you get the bonus weapon in the first playthrough.
** [[DoesThisRemindYouOfAnything It gets bigger when he holds Yorda's hand]].
* The one-use laser knife from ''VideoGame/OverBlood''.
* ''VideoGame/{{Touhou}}'' has Flandre Scarlet and her Lavaetein. I believe it's supposedly made out of fire, but hey, this is a bullet hell shooter. It sure LOOKS like a Laser Blade to me.
** In official art, its inactive form looks more like an oddly-shaped wand or whip.
** Hinanawi Tenshi's Sword of Scarlet Thought also applies, at times.
* ''VideoGame/WorldOfWarcraft'' has a few of those available to players. Among them the retardedly rare, and thus disgustingly expensive, Teebu's Blazing Longsword. Many players probably don't even know this weapon exists. It's that rare.
** A total of four of these exist in WoW - A red one, which is a rare world drop, a bright orange/pink one which is also a rare world drop, and two blue ones - one is a quest reward, the other has a chance to drop off a boss inside an instance. The blue ones can be enchanted with a fire enchant, which makes them glow purple.
** At least one more was added in Cataclysm. This one is actually called a "Very Light Sabre", and is among the best weapons you can possibly get at the time of the quest... which is level 3 - and exclusive to gnome warriors. Each gnome class gets its own StarWars ShoutOut, from the Death Star (rogue mace) and Staff of the Force (priest staff), to the decidedly more obscure Vibro Knife (warlock dagger) and Electro-Staff (mage staff).
*** There's also the Runeforging ability Death Knights get that can be used on swords, that while not making the swords in question in question ''true'' {{Laser Blade}}s, they glow vividly just like real ones.
* ''VideoGame/BattleRealms'' gives the Ronin and Samurai swords that can turn into these. The Wolf Clan Dryad starts off with ''nature-powered {{Laser Blade}}s''.
* In the second ''VideoGame/WarriorsOrochi'' game, Yoshitsune Minamoto has a special gauntlet that produces an energy blade. Said gauntlet and blade can even fire energy blades.
* Constructor X from ''VideoGame/BombermanGeneration'', who forms one from his drill-arm and causes [[StuffBlowingUp explosions when swung]].
--> I will destroy you, '''[[LargeHam WITH MY LASERBLADE]]!!!'''
* ''Multi-Dimensional Thief'', an old text adventure game, parodies the ''StarWars'' lightsaber. It can cut anything as long as it's an inventory object, and some versions of the game allow the lightsaber to either cut itself or your fingers (without ill effects other than losing the lightsaber.) Just don't go through a hole while carrying it.
* Another, lesser known Capcom example is Hayato Kanzaki from ''VideoGame/StarGladiator'' who wielded a laser blade weapon as well. Of course, [[MarthDebutedInSmashBros people will remember]] more his inclusion in ''VideoGame/MarvelVsCapcom2''. There are also other types of plasma weapons than just sword (which have different variations like [[{{BFS}} broadsword]] and [[RoyalRapier rapier]]) like rings, yo-yos, axes, maces and so forth.
* ''VideoGame/{{Aion}}'' currently has a weapon skin called the "Aether Blade" which can be purchased from their website and used to remodel your character, while it doesn't extend the way a StarWars style Light Saber would, it does strongly resemble one while remaining legally distinct from it.
* Not merely content to show Amaterasu up and be a general thorn in her paws, Waka in ''VideoGame/{{Okami}}'' had to have a better sword than Ammy to boot! While she has to make due with metallic blades (made of divine metals, mind you, but metal nonetheless), he gets the LaserSword... and a LaserSword that extends from inside of his flute! Showing her up that bad ought to be considered blasphemy if not a mortal sin!
** While it does nothing to alleviate the injustice done to Amaterasu, the player can finally get a chance to use [[InfinityPlusOneSword Waka's sword]] in ''VideoGame/{{Bayonetta}}'', granted that they can complete the game on the highest difficulty level to obtain it. It might appear to be [[BraggingRightsReward worthless]] if one had to tackle the [[IdiosyncraticDifficultyLevels Non-Stop Infinte Climax]] [[HarderThanHard Mode]],but there's [[BonusBoss one last being left to challenge]] who justifies use of so much power and then some.
** Of course one could just ignore that difficulty and input the cheat code instead.
* Also we have Master Yi's skin,Chosen One in ''VideoGame/LeagueofLegends''. He wears a lightsaber!
* ''VideoGame/ShadowHearts'': Johnny Garland has one, but it's less a laser blade and more pure evil channeled into his knife.
* ''VideoGame/{{Fraxy}}'' gives us this exact blade in three lengths!
* ''VideoGame/{{Wizardry}}'' being full of SchizoTech, the top sword of the last three games is the Light Sword - a Lightsabre that your warriors in full plate can wield.
* ''VideoGame/GuildWars2'' has several swords that could qualify, from the [[https://wiki.guildwars2.com/images/f/f2/Holosmith%27s_Sword.jpg Super Adventure Box sword/greatsword skins]] (which are holographic and transparent energy); the [[https://wiki.guildwars2.com/images/6/6a/Chaos_Sword.jpg Chaos sword]] (the entire weapon is white light shaped like a sword); or the Black Lion shop's [[https://wiki.guildwars2.com/images/e/e0/Plasma_Sword.jpg Plasma Sword skin]], which looks remarkably close to a lightsaber. And then Path of Fire was released, introducing several new class specializations- one of which was the Holosmith, who could use a "Holo-Forge" to create hard light constructs, and who could use swords. Their special skin is [[https://wiki.guildwars2.com/images/f/f2/Holosmith%27s_Sword.jpg the Holosmith sword]]- which looks ''exactly'' like a lightsaber, it even recedes into the hilt when not in use.
* Sword-wielders in ''VideoGame/CityOfHeroes'' can get these as unlockables. There's even a laser axe. No change in power and they still do the same type of damage, but hotly pursued nonetheless.
* ''VideoGame/ShinMegamiTenseiI'' has Plasma Swords as a weapon usable only by Law Hero (or a lawful Main Character). Since items didn't have graphics in that game, we don't really know what it looked like, though.
* ''VideoGame/ShinMegamiTenseiIIINocturne'' has the Hito-Shura generate one from his hand when using an attack that requires a weapon.
* ''Franchise/{{Castlevania}}''
** The most powerful one-handed sword in ''VideoGame/CastlevaniaCurseOfDarkness'' is a laser sword, but getting all the components to [[ItemCrafting craft it]] takes some work.
** In ''VideoGame/CastlevaniaOrderOfEcclesia'', combining the [[FrickingLaserBeams Nitesco glyph]] with any weapon glyph will make Shanoa smack the enemy with a Laser {{BFS}} several times her own size. This is the strongest attack in the game, and sufficiently boosted it can take even Dracula himself out with just a few swipes.
* [[spoiler:Kanon]] of ''VisualNovel/UminekoWhenTheyCry'' busts out a laser blade in the fantasy scenes.
* The Komato Assassins in ''VideoGame/{{Iji}}'' have laser daggers.
* ''VideoGame/{{Xenoblade}}:''
** [[SwordOfPlotAdvancement The Monado]] is a particularly odd example. It looks like an odd {{BFS}} while inactive, but while active, the blade opens up to reveal an even bigger laser blade, capable of getting big enough to be wielded by the Bionis, a titan [[WorldShapes whose body makes up half the known world!]] Even when being wielded by Shulk, the blade is quite large, and the Monado Buster attack makes the blade extend to a truly ridiculous length for the duration of a single strike.
** There are also more "mundane" laser blades [[spoiler:courtesy of the Machina]] in the form of swords for [[TeamDad Dunban]] [[spoiler:and replicas of the Monado for Shulk]].
* ''VideoGame/XenobladeChroniclesX'' has the Photon Saber weapon type, used by the Blast Fencer and Galactic Knight classes. Additionally, [[HumongousMecha Skells]] have access to many varieties of beam weaponry; alongside regular laser swords, [[DoubleWeapon double sabers]], [[RingsOfDeath ring blades]], and [[SinisterScythe beam scythes]] are all on the table.
* In ''VideoGame/MassEffect3'', [[PlayerCharacter Shepard]] gains access to the omni-blade, a modification to the standard omni-tool that unfurls out to create a searing hot silicon-carbide blade, suspended in mass effect fields. The in-universe explanation for their sudden appearance is that they had been designed years ago but were considered [[AwesomeButImpractical useless]], since enemies rarely would get into close-quarters enough for them to be used.
** There are many versions of this because every class wields their own melee weapon (Though they are not all blades) such as the sentinel who wields two omni blades, infiltrators with two-pronged electrified blades, or engineers, who simply slam a flaming silicon-carbide disc into their enemies with the back of their hand.
** It's also worth noting that Omni-blades are not laser blades or hardlight, but the suspended 'blade' is invisible on it's own. The Omni-tool creates a holographic sheathe to provide visual context for the user and allies.
* One type of the [[{{Mooks}} standard enemies]] as well as one of the boses of the old arcade game ''Xain D'Sleena'' (aka: ''Solar Warrior'') use laser blades (the former to attempt to impale your character with them). If they hit you, [[OneHitKill you are dead]], no matter how much life you've remaining.
* At least one character in ''[[VideoGame/EscapeVelocity EV Nova]]'' is noted to have a "laser rapier" hooked to his belt.
* The Gigawatt Blades in ''VideoGame/InFAMOUS''
* ''VideoGame/SaintsRowIV'' gives us the Laser Razor, which is shaped like a katana, but is otherwise closely resembles the classic Jedi weapon. And yes, there are ''Star Wars''-themed costumes, too.
* ''VideoGame/{{Terraria}}'' has six colors of Phaseblade, which can be upgraded to the Phasesaber, and make the classic lightsaber noises when swung.
* The Masked Man in ''VideoGame/{{MOTHER 3}}'' wields a lightsaber as part of being a DarthVaderClone. It has the ability to shoot intense bolts of lightning that instantly knock the target out.
* ''VideoGame/FalloutNewVegas'' has the "Protonic Inversal Axe" which is some kind of suspended forcefield on a pole. It does extra damage to robots, and the [[MadScientist Think Tank]] decided to make a ''throwing version''.
* The Player's mecha, ''Jehuty'', in the ''VideoGame/ZoneOfTheEnders'' games have these, as well as ''Dolores'' from ''Dolores, i'' and ''Testament'' from ''[[VideoGame/ZoneOfTheEndersTheFistOfMars The Fist of Mars]]''.
* The player uses them in ''VideoGame/SinAndPunishment'' to deal with enemies who get too close.
* The Cyphers from ''VideoGame/{{Strider}}'' are a mix of this and HotBlade, as they [[AbsurdCuttingPower cut through stuff like tanks]] by creating a blade of high-voltage, accelerated plasma.
** TheRival Strider Hien's weapon is a [[DoubleWeapon Double Cypher]] who uses the same principle as a ''Laser BattleBoomerang''.
* Probably one of the less conventional examples, but ''VideoGame/GhostsNGoblins'''s Arthur can turn knives into FrickinLaserBeams through magic.
* This is Mike Matei's main weapon in ''VideoGame/TheAngryVideoGameNerdAdventures''.
* Some of the mecha in ''VisualNovel/{{Sunrider}}'' use laser blades.
* ''Videogame/{{Warframe}}'' has the Gram, a Tenno {{BFS}} which uses a blade made of plasma on each side of the weapon to cleanly slice enemies to bits. Its smaller brother, the Plasma Sword, functions pretty much identically (and originally, the Gram was just a [[PaletteSwap giant version of the Plasma Sword]]). The "Ether" weapons ([[SinisterScythe scythe]], daggers, swords) use an AbsurdlySharpBlade made from plasma.
* The final upgrade for the Boomerang Monkey in ''VideoGame/BloonsTowerDefense'' 4 allows it to throw spinning lightsabers through hordes of bloons! Oh, and it can pop through lead bloons, being a laser and all.
** But for some reason, a Laser Vision Super Monkey can't...
*** A Laser Cannon Dartling Gun can though! (Well, only in 4, not 5)
* In ''Videogame/DragonAgeInquisition'' the Knight Enchanter PrestigeClass for mages grants abilities and bonuses that allow the normally SquishyWizard to become a formidable MagicKnight. One of these abilities is "Spirit Blade", a powerful and close-range Laser Blade made of magic. The initiation test (i.e. the sidequest the player needs to take to access the specialization) is to construct the blade's hilt, and just in case someone missed the parallels to Jedi lightsabers, the Spirit Blade can also be upgraded to automatically [[AttackReflector redirect incoming ranged attacks back at the shooter]].
* ''VideoGame/XCOMApocalypse'' has "plasma sword", one of Earth improvements over alien plasma weapons from the first game. When off it looks like a long and narrow serrated metal cone with a handle and a guard. When on it is engulfed by plasma. In game terms it is a plasma gun with very short range (1 square, sometimes 2 because of a bug) but unlimited ammo and highest damage. (Rockets and explosives do 2-4 times more damage, but the sword has higher fire rate.) Unfortunately they only appear in stores 1-2 weeks after the game starts and are always in short supply -- by the time you get enough for the whole squad, you would already have armed them with captured heavy disruptors (10% weaker, but with unlimited range).
** "Thermal lances" from ''XCOMTerrorFromTheDeep'' may also qualify. Those are alien heated drills used as close combat weapons.
* ''VideoGame/{{Mabinogi}}'' has [[http://wiki.mabinogiworld.com/view/Beam_Sword Beam Swords]], rare event-reward weapons with low consistency but very high damage. They have three grades, Bargain, regular and Focused, and also a lesser ranking based on color. They cannot take upgrades, and being Mabinogi weapons, their high damage comes at a cost of being very expensive to repair when they get worn.
* ''VideoGame/SenranKagura''
** Leo uses a nodachi-sized laser sword with a western-style handle, guard and all, and also having a sheath to it. Her sister Hyoki also uses one, though her sword looks like a regular sword at first before turning into a laser blade.
** In ''Senran Kagura 2: Deep Crimson'', one of the {{Joke Weapon}}s for Ultimate Asuka and Crimson Homura are "Twin Beam Swords" and "Single Beam Sword" respectively. And not only do they look like ''Franchise/StarWars'' lightsabers, but [[TheHero Ultimate Asuka]] has blue and green ones where as [[TheRival Crimson Homura]] has a red one.
* Ultra V of ''VideoGame/WarOfTheMonsters'' uses a laser katana in its short range special move.
* [[OurAngelsAreDifferent Archons]] from ''VideoGame/NexusClash'' have a holy Blade of Light that basically functions as one of these. They're especially good at dispelling wards and magical defenses and purging evildoers. Some Archons may have a very [[BlackAndWhiteInsanity broad]] definition of 'evildoers'.
* ''VideoGame/{{Persona 5}}'': Your final party member, Goro Akechi, uses a handle device that produces a sword of pure white energy as his melee weapon.
* In ''VideoGame/FateGrandOrder'', Mysterious Heroine X and her Alter form are parodies of Star Wars characters, so their Noble Phantasms are lightsabers.

[[folder:Visual Novel]]
* In ''VisualNovel/StarshipPromise'', officers of the Galactic Liberation Front (aka The Empire) wield beam sabers, and can use them to deflect blaster fire. Captain Antares Fairchild has a red-bladed one, which he seems to prefer over firearms.

[[folder:Web Animation]]
* ''WebAnimation/{{Haloid}}''. Samus has one that not only cuts things but acts as a tractor beam, blaster and stasis field generator.
* In ''Machinima/RedVsBlue'', Tucker ends up with an energy sword that works only for him (much to Tex's dismay). It also briefly functions as a key.
-->'''Caboose:''' Or maybe it's a key all the time, and when you stick it in people, it unlocks their death.

* The multi-purpose "aser-blades" (not a typo) in the space arc of ''Webcomic/ArthurKingOfTimeAndSpace''. Described in full in [[http://www.arthurkingoftimeandspace.com/0057.htm this strip]], including comparision to a lightsaber (without actually saying "lightsaber").
* Darth Maul sells Zexion lightsabers in ''Webcomic/AnsemRetort''. He claims to have a hundred of them in his car to sell to StarWars geeks for organs.
** Note that Zexion hasn't really used them since season one, unlike Darth Maul and Xemnas, who use them to this day.
* In keeping with the general theme of the comic, ''Webcomic/DarthsAndDroids'' offers humorous alternate explanations for the use of lightsabers. GM "just took a D&D equipment list and [[SciFiNameBuzzwords stuck techy words in front]]", Qui-gon and Obi-wan only have lightsabers because they didn't start off with enough money to buy blasters, and the Jedi are able to block blaster fire because the players fast-talked the GM into letting them do so.
** And, to boot, they always use the "laser sword" terminology in lieu of "lightsaber".
** Cory never liked using one given how obviously unsafe they are, and he's playing Luke. After getting his hand cut off and losing his original, he had no plans to use on again. Circumstances forced his hand, however.
* ''Webcomic/{{Sinfest}}'' has a [[http://www.sinfest.net/view.php?date=2010-08-15 laser scythe.]] Because why not to walk this one to the end.
* ''Webcomic/GunnerkriggCourt'' has [[http://www.gunnerkrigg.com/archive_page.php?comicID=688 Coyote's Tooth]] looking like this, at least [[http://www.gunnerkrigg.com/archive_page.php?comicID=965 in one of its forms]] when unsheathed. This thing doesn't hum -- it ''[[TheHyena laughs]]''.
* Wielded by [[CuteKitten Fluffy]] in ''Webcomic/CommanderKitty. [[http://www.commanderkitty.com/2010/05/16/spaceouts/ Of course,]] it's just an ImagineSpot.

[[folder:Web Original]]
* Spencer uses a ''StarWars'' type lightsaber in the ''WebVideo/Lonelygirl15'' episode "We Have A Plan".
* In the Literature/WhateleyUniverse, Tennyo can generate a "laser blade" made of anti-matter. How she ''makes'' anti-matter at will is a whole 'nother problem. WordOfGod says the devisors and gadgeteers can't make working lightsabers, even though they all try, sooner or later. It is later clarified that while you can't build a working gadget-only lightsaber, you can build one as a [[MadScience devise]], but powering it for any length of time is nearly impossible; one Energizer solves this problem by powering hers with her own energy field.
* ''WebVideo/StupidMarioBrothers'' uses them like in VideoGame/SuperSmashBros, but they are [[WritingAroundTrademarks called Beam Swords]].
** which gets Lampshaded by Wario and Mario in Season 4
--> Wario: So why do we fight with Li.... uhh I mean Beam Swords?
--> Mario: I don't know. They use them in Super Smash Brothers.
* Michum's WeaponOfChoice in ''Literature/ThePiratesCoveredInFur'' is a green beam sword.
* ''Creator/{{The Autarch}}'' gained a power to use Aerial Blades in the end of his Top 25 Boss Battles. They have been his "trademark power" ever since.

[[folder:Western Animation]]
* The Sun Sword from ''WesternAnimation/ThundarrTheBarbarian''.
* [[WesternAnimation/GaltarAndTheGoldenLance Galtar and his golden lance]] does the Darth Maul version.
* Skysurfer One's primary weapon in ''WesternAnimation/SkysurferStrikeForce''.
* In animated ''WesternAnimation/TeenTitans,'' there's an extremely fanboyish villain named Control Freak who, it turns out, is a decent fighter due to ''Film/TheMatrix''-style programmed skill. His weapon of choice is a light-lance made of two sets of dual beams. (The colors are red, blue, green, and purple, the four colors of lightsabers in the ''StarWars'' movies.)
* WesternAnimation/KimPossible fights some {{Ninja}}s in TheMovie who wield energy swords.
* In the pilot episode of the ''[[ComicBook/BuckyOHareAndTheToadWars Bucky O'Hare]]'' cartoon, Deadeye Duck freaks out because he thinks the "hairless ape" intruder (actually human Willy) is packing a lightsaber (he actually says "lightsaber", too). Turns out it's just a generic flashlight.
* ''WesternAnimation/SheRaPrincessOfPower'' featured energy blades in the hands of some secondary characters, meaning they weren't even close to most powerful thing around in that universe.
** Your mileage may vary...in one episode She-Ra's friendly aerial pirate is trapped in a subterranean cave with an ominous charachter who totally pwns him in personal combat due to various gadgets much cooler than the ones he had access to. The most severe pwnage occurred when said character lighted up a "photon cutlass" with which he sent poor Hawk flying freely around after he tried to deflect a blow with his mere "laser sabre". So photon cutlasses packed punch in She-Ra's universe!
*** Moreover the asskicking character was later revealed to be Hawk's long-lost pirate father who was just fooling around and testing his kid's mettle. In the end he donated all of his asskicking equipment to his son.
* Subverted by ''WesternAnimation/TheVentureBrothers'' in "Tag Sale - You're It!". Dr. Venture throws a yard sale, and [[MauveShirt Henchmen #21]] purchases a prototype laser sword that was rejected by the Army. #21 later attempts to take on [[HeroicComedicSociopath Brock Samson]] with his new toy, [[HilarityEnsues with predictable consequences]] when it's demonstrated that the prototype is a glorified flashlight.
** "[[RealityEnsues The Army said 'we don't swordfight anymore', and]] Creator/{{Kenner}} [[RealityEnsues wasn't interested in a toy that cost over $2 million in parts alone.]]"
* The eponymous ''GiantMecha'' in ''WesternAnimation/MegasXLR'' has an energy sword, activated by Coop hitting the ''BigRedButton'' Labelled [[ExactlyWhatItSaysOnTheTin "That cool energy sword thing"]]
* The first episode of ''WesternAnimation/BatmanTheBraveAndTheBold'' has Batman storing one of these in his utility belt. Where did it come from? Why does he only use it once? Doesn't it violate his [[TechnicalPacifist technical pacifism]]? Who cares? It's ''[[NinjaPirateZombieRobot Batman with a lightsaber!]]''
** Not just once; in a later episode's [[BatmanColdOpen cold open]], he [[DualWielding dual-wields]] it alongside a ''demon's sword''.
* The ''WesternAnimation/BatmanBeyond'' [[VillainOfTheWeek villain]] Payback use a laser whip that double as sword. [[spoiler:It was used to make statues for a Youth Counseling Center before the villain repurposed it.]]
** A scene inside a chop shop showed crooks slicing up stolen cars with a laser chainsaw.
* In ''WesternAnimation/ZorroGenerationZ'' ''everyone'' has laser swords, and a lot of people have laser whips. Since it otherwise seems to be ThePresentDay, it's not clear [[FamilyFriendlyFirearms where they came from]], but it wouldn't be ''{{Franchise/Zorro}}'' without cool swordplay.
* The eponymous hero of ''Anime/{{Ulysses 31}}'' wields a "Raypier" which doubles as an energy pistol and a laser sword. For defence, he has an energy shield (think ComicBook/CaptainAmerica when his usual shield was stolen) which he wears on one wrist like a watch.
* Parodied in ''WesternAnimation/{{Futurama}}'': police officers use lightsabers as non-lethal batons.
** They even have laser ''handcuffs''. Apparently these so-called "lasers" in the Futurama-verse are actually some kind of luminous force-fields.
*** [[StateTheSimpleSolution it could be]] [[Main/HardLight Hard Light]] in effect.
* In ''WesternAnimation/TeamoSupremo'', Laser Pirate's main weapon is his laser hook, which can morph into other weapons, such as a laser blade and a laser cannon.
* The "how is a laser stopping at an arbitrary distance" problem is [[ConversationalTroping conversed]] in ''WesternAnimation/ClerksTheAnimatedSeries'':
-->'''Randal''': The light sabers in ''StarWars''. You turn it on, and it goes ye high. How does it know when to stop?\\
'''Dante''': [[AWizardDidIt The Force]]?\\
'''Randal''': That's your excuse for everything!
* ''WesternAnimation/DeadSpaceDownfall'' has laser chainsaws; sadly, these do not appear in the game.
* Duke L'Orange in ''WesternAnimation/TheMightyDucks'' has one.
* In 1987, there was a U.S.-produced series called ''WesternAnimation/HelloKittysFurryTaleTheater'', with Sanrio's eponymous character and her friends parodying fairy tales, and even popular movies. One episode featured a parody of ''Franchise/StarWars'', complete with Tuxedo Sam (who played the Luke Skywalker character) and Catnip (who played the Darth Vader character) having a lightsaber fight (which also happens in the TitleSequence). The episode "Paws of the Round Table" had all the swords, including Excalibur, replaced with lightsabers.
* In the ''WesternAnimation/JusticeLeagueUnlimited'' episode "The Once and Future Thing" Part II, One of the Jokerz gang working for the time travelling villain Chronos, uses a double-bladed red lightsaber as a weapon. May count as a possible ActorAllusion when you consider the [[Creator/MarkHamill voice actor for The Joker in the prequel series.]]
* Kat wields one in the ''WesternAnimation/KidVsKat'' episode "Play N'Ice".
* Seen a couple of times on ''WesternAnimation/AdventuresOfTheGalaxyRangers'', mostly among space pirates and other low-level thugs.
* In an episode of ''WesternAnimation/AvatarTheLastAirbender'', Aang says that what he needs to complete his ScaryImpracticalArmor ensemble is a "wind sword."
-->'''Katara:''' What's a wind sword?\\
'''Aang:''' It's where I get a sword handle, and then I just swing this around and [[BlowYouAway bend air out]] [[RazorWind like a blade.]] (makes lightsaber noises)
* In ''WesternAnimation/Ben10UltimateAlien'', the unified Forever Knights now wield them.
* ''WesternAnimation/YoungJustice'': Whisper wields a pair of laser whips against Superboy and the Forever People in "Disordered".
* One episode of ''WesternAnimation/TransformersGenerationOne'' has Optimus able to create an axe-version of this, which Megatron responds to with a flail-version.
* The leader of the Fearsome Hand of Four in ''WesternAnimation/BatmanUnderTheRedHood'' dual-wields a pair of these.
* ''Series/TheSuperMarioBrosSuperShow'': "Star Koopa" spoofed these with "Lightplungers", as in lightsabers whose hilts looked like tiny plungers. The beams functioned more like batons as they do not cut anything. Instead, they electrocute whatever they hit.

[[folder:Real Life]]
* On his ''Sci-Fi Science'' television series, Dr. Michio Kaku explored the possibility of making a real-life lightsaber out of an extended plasma torch. Unfortunately, this required trillions of nanobatteries, theoretical superceramics, and enough electricity to ''power a small city.'' This may be viable in the long-term, but unlikely for the next few decades. Still prone to WhyDontYouJustShootHim, though: that level of technology could easily make powerful guns which are more practical anyways. The main practical application of this would be as an extremely effective chainsaw that could cut through virtually any material, though at extreme danger to the user, but it's not as if plasma cutters are exactly safe to begin with.
** As an aside, the "nanobatteries" would have an energy density of [[http://scienceblogs.com/dotphysics/2010/02/02/power-source-for-a-lightsaber/ 470 MJ/L.]] That's about [[https://en.wikipedia.org/wiki/Energy_density#Energy_densities_of_common_energy_storage_materials 117 times the energy density of Jet fuel.]] Shoot the lightsaber. The resulting explosion would take out everything within a hundred feet.
* A thermal lance (some may recognize them from ''VideoGame/FalloutNewVegas'') is a real-world device that some liken to a lightsaber. It essentially burns iron rods to create an intense stream of heat out one end, like a gigantic blow torch but much hotter. Granted they are much bigger than a lightsaber hilt and would require two hands to wield, but the stream to project has all the cutting power: they are normally used to cut through solid concrete and steel girders.
