[[SayingSoundEffectsOutLoud PEW! PEW! PEW!]]

Any gun that shoots light, rays, waves, or something similar. Initially popular during the appropriately named RaygunGothic era of ScienceFiction, but back then it was based on pure {{Phlebotinum}}, as shooting such things from weapons wasn't known to be possible. In short, the ray gun was falling out of favor for being unrealistic. Then [[LifeImitatesArt the laser was discovered]] in TheSixties. Suddenly the RayGun was [[ScienceMarchesOn brought back]] from being a DiscreditedTrope.

But even now it's still treated as an ImpossiblyCoolWeapon, as lasers in fiction [[ArtMajorPhysics are often used in ways they can't really be]]. And while other ray guns do exist in RealLife (the US Army has been experimenting with microwave crowd dispersal wave generators, for example), they're still CoolButInefficient.

The term "ray gun" became a cliché even by the 1940s, having strong associations with BuckRogers, ComicStrip/FlashGordon etc., and from at least Creator/EEDocSmith's ''Literature/{{Lensman}}'' novels, was increasingly replaced by the more bad-ass-sounding generic "blaster", Smith himself generally choosing to refer to the weapons by their maker just as we would refer to a Colt or Smith & Wesson.

They are also popular as a form of FamilyFriendlyFirearms.

A SubTrope of EnergyWeapon, ImpossiblyCoolWeapon.

A SuperTrope to:
* DeathRay
* DisintegratorRay
* FreezeRay
* FrickinLaserBeams (lasers specifically, and plasma weapons to a lesser extent)
* HypnoRay
* LightningGun
* PlasmaCannon
* ReflectingLaser
* ShrinkRay
* StunGuns (non lethal, usually energy)
* TransformationRay
* WaveMotionGun

A SisterTrope to LaserBlade.

Compare PureEnergy.

Not to be confused with [[Manga/YuYuHakusho ReiGun]], [[MagneticWeapons Railgun]], [[UsefulNotes/RonaldReagan the president]], [[Franchise/StarWars Nute Gunray]] or [[Anime/NeonGenesisEvangelion the Rei]] or [[ReiAyanamiExpy a Rei]] with a gun.

!!Examples

[[foldercontrol]]

[[folder:Comic Books]]
* The ray guns in the old serials like ''ComicStrip/FlashGordon''.
* [[AnIcePerson Mr. Freeze's cold ray]] in ''Franchise/{{Batman}}''.
* ''ComicBook/BuckGodotZapGunForHire''
* Common among spacers, but tightly controlled in Warren Ellis' IgnitionCity.
[[/folder]]

[[folder:Film]]
* Blasters and turbolasers in ''Franchise/StarWars''.
* The antimatter guns in ''Film/TheRockyHorrorPictureShow''.
* ''Film/SkyCaptainAndTheWorldOfTomorrow'' has Dex build one for the protagonist. It's unreliable and the shots are a parody of SpecialEffectsFailure: goofy slowly spreading rings straight out of period comics and cheap science fiction. However, it's very impressive at melting Totenkopf's robots.
* In ''ComicBook/ReidFlemingWorldsToughestMilkman'', Reid receives a ray gun as a Christmas present from his mother. When he also receives a prank gift from Mr. Crabbe, Reid decides to try out his new ray gun on Crabbe's roof.
[[/folder]]

[[folder:Literature]]
* In one Creator/IsaacAsimov book they use "atomic ray guns" that apparently boil the blood of any organic thing hit until it explodes. In the Literature/{{Foundation}} series, they use Atom Blasters (shortened to just "blasters" in the later books, after the age of AtomPunk had passed).
* The short story "[[http://www.thinkage.ca/~jim/raygun.htm The Ray-Gun: A Love Story]]" is about a ray-gun.
* One ''Literature/{{Biggles}}'' story mentions these as a possible explanation for the inexplicable crashes of multiple Allied aircraft flying a particular supply route. It turns out to be something rather simpler: [[spoiler:Japanese intelligence officers were slipping packets of chewing gum laced with a powerful narcotic into the cockpits of the planes, causing the pilots to pass out at the controls.]]
* Creator/ArthurCClarke, always a stickler for hard science in his short stories, subverts this. A group of pub patrons lampshade this trope while arguing whether ray guns can even exist, prompting one to tell a story within a story of an astronomer that [[spoiler: uses a highly polished mirror to reflect his wife's headlight beams back in her face when she's driving home from one of her trysts - attempting to murder her by driving her off a dangerous road. Unexpected outcome ensues. It wasn't the tryst that annoyed him - is was the light pollution from her headlights interrupting his studies of the heavens that drove him to such measures.]]
* Literature/NorthwestSmith uses a "Heat Gun" in the stories by C.L. Moore.
* Used in the tagline of TheChroniclesOfProfessorJackBaling: Brilliance. Madness. Ray Guns.
* ''Literature/MarkDelewenAndTheSpacePirates'' has Mark and Tirt using one each; in stun mode.
[[/folder]]

[[folder:Live-Action TV]]
* Phasers and disruptors in ''Franchise/StarTrek''.
** The tie-in ''Star Fleet Technical Manual'' actually features a weapon called a 'ray gun', although this is actually a mislabelled prop used in the show as a signal beacon.
** The ''Captain Proton'' [[ShowWithinAShow holodeck program]] in ''Series/StarTrekVoyager'' has your typical black-and-white {{Zeerust}} look, including ray guns and [[EvilGenius Dr.]] [[LargeHam Chaotica's]] DeathRay. When Paris is coaching Janeway on how to act inside the program, he reminds her to use the term "ray gun" instead of "phaser".
* The "Lassiter," a laser gun stolen by the crew of Serenity in the ''{{Firefly}}'' episode "Trash".
** Also the laser gun used by Rance Burgess in "Heart of Gold".
* The overabundance of "ray guns" of similarly-cheesy design in scifi is lampshaded on ''Series/DoctorWho'', when the Doctor is shown a bunch of unidentified alien devices suspected, largely on the basis of shape, of being weapons. As he searches for something that might actually hurt the MonsterOfTheWeek, he tosses aside the rejects, reciting:
--->'''Doctor:''' Broken... broken... hair dryer...
* ''Series/RedDwarf'''s bazookoids are mining lasers used as weapons.
* Common in ''PowerRangers'' and ''SuperSentai''. The best-known would probably be MightyMorphinPowerRangers' Blade Blasters, which also become dirks.
[[/folder]]

[[folder:Pinball]]
* All of the futuristic explorers in {{Atari}}'s ''Pinball/MiddleEarth'' pinball are armed with either {{Laser Blade}}s or Ray Guns. Makes sense, given that they're exploring a LostWorld filled with [[{{Kaiju}} giant dinosaurs]] and [[KillerGorilla monster apes]].
* The unnamed male character in ''Pinball/TheAtarians'' uses one.
* Stewie Griffin in Creator/SternPinball's ''Pinball/FamilyGuy'' shoots the letters in P-I-N-B-A-L-L with one.
* Used by the spaceships in ''Pinball/StellarWars''
[[/folder]]

[[folder:Tabletop Games]]
* {{Mekton}} has an elaborate construction system for equipment from switchblades to planet-killing space fortresses, including a dizzying array of "Beam Weapons" (ray guns).
* ''TabletopGame/{{Warhammer 40000}}'' has a number of ray-gun-wielding troops. For brevity's sake, probably the most exotic is the Necron Gauss Flayer, an electromagnetic DisintegratorRay that can break down the magnetic charges that hold matter together. The catch? The ray has to be fired through a crystal with exact specifications, right down to the atom, so it's virtually impossible for any other race to emulate.
** Also, it works by ''tearing off the flesh of its victims one layer of molecules at a time. First skin, then flesh, then muscle, then bone...''
** The standard Imperial raygun are classified as 'las weapons'. They fire a laser beam capable of blowing a man's arm off. Though they're [[RunningGag unfavorably compared to flashlights]].
* ''TabletopGame/{{Paranoia}}'' has laser pistols and rifles, energy pistols, blasters, stun guns, and [[{{BFG}} plasma generators]].
* ''{{Traveller}}'' naturally offers a range of laser, plasma, and fusion weapons to meet all your needs.
[[/folder]]

[[folder:Video Games]]
* The ''VideoGame/{{Quake}}'' series has a few. The original ''[[VideoGame/QuakeI Quake]]'' features the Enforcer enemies, who are soldiers with laser guns which shoot reddish-yellow projectiles. ''VideoGame/QuakeII'' has the infinite-ammo blaster gun, an unusual example of a ranged EmergencyWeapon. The {{Rail Gun}}s can be considered to be {{Ray Gun}}s too.
* All three ''VideoGame/SuperSmashBros'' games have the "Ray Gun" item. Unlike some other energy weapons though, it only has 16 shots.
* ''VideoGame/CallOfDuty: World at War'', of all games, has a ray gun, by name, available randomly in the Nazi Zombies bonus mode and [[http://www.youtube.com/watch?v=WDjR3vkOQeU sneakily hidden in one of the singleplayer levels]], along with its larger cousin, the Wunderwaffe, on a downloadable map. The former fires green rays surrounded by rings, and the latter some sort of electricity. Both have a very retro RaygunGothic look to them, and are very good at killing zombies.
* Several of the weapons in ''TheConduit'' are various forms of ray guns. To give but two examples: the Carbonizer Mk16 fires a giant beam that cooks enemies from the inside, and the alien Strike Rifle can be charged to fire a OneHitKill beam.
* Aside from the obvious example of the alien blaster, the ''VideoGame/{{Fallout}}'' series has a number of weapons resembling ray guns, such as the laser, plasma, [[MagneticWeapons Gauss]], and (most especially) pulse guns.
* ''VideoGame/TeamFortress2'': One of the Soldier's many, many alternate weapons is now a small handheld ray blaster or a larger ray gun.
** The Engineer and Pyro now have ray guns of their own, although predictably the Pyro's new primary still has range issues.
* In the first ''VideoGame/NoOneLivesForever'' game, you can find and use a retro-looking laser gun on the [[FunWithAcronyms HARM]] space station. It instantly disintegrates the target and has enough charge for about 500 shots.
* Blasters in ''VideoGame/MightAndMagic''. Mainly VI and VII, since that's where we actually got to ''use'' them (yes, this is a game series where [[ScienceFantasy a mage can mow down liches using a blaster rifle]]).

* An episode of [[http://www.youtube.com/watch?v=QZkqC4Lz8dU How it Should Have Ended]] mocks this trope, showing a member of the avengers shouting "Pew! Pew! Pew!" while firing.
* Yaeger's pistol, the ''Lumiére'', in ''TheMercuryMen''.

[[folder:Real Life]]
* Although they turned out to be mistaken, Allied advisers who learned of the plans for German "reprisal weapons" in the mid-years of UsefulNotes/WW2 put both "death rays" and "engine-stopping rays" higher on the list of suspects than "long-range rocket missiles".
** Apparently ''radar'' originally came to the attention of the British government after they put out a request for proposals for directed-energy weapons.
* Appropriately enough, UsefulNotes/NikolaTesla developed plans for his "Teleforce", essentially a particle-beam weapon, but unfortunately ([[MadScientist fortunately?]]) never actually built a working device.
