[[caption-width-right:350: Limbo lower now! How low can you go?]]

->''"There is one neat effect when characters unwisely venture into a corridor and the door slams shut on them. Then a laser beam passes at head level, decapitating one. Another beam whizzes past at waist level, cutting the second in two while the others duck. A third laser pretends to be high but then switches to low, but the third character outsmarts it by jumping at the last minute. Then the fourth laser turns into a grid that dices its victim into pieces the size of a Big Mac. Since the grid is inescapable, what were the earlier lasers about? Does the corridor have a sense of humor?"''
-->-- '''Creator/RogerEbert''', in his review of the first ''Film/ResidentEvil'' movie

Whenever there's a security system in place, there's always a highly visible laser sensor grid with man-sized holes in it. The infiltrator must then use cunning acrobatics or clever trickery to navigate around the lasers to reach the target on the other side. Or, if he's Series/MacGyver, he can rig up a cunning system of mirrors to deflect the lasers around himself.

Often, the grid can be disabled briefly without triggering the alarm, usually just long enough for the intrepid heroes to sprint the length of the hall/gallery/vault in question. Unless the plot calls for them to be caught, in which case the grid will re-activate an instant too soon. Sometimes the beams are invisible to the naked eye, requiring some AppliedPhlebotinum to make them visible; this may take the form of an aerosol spray or high-tech goggles. Or just cigar smoke. Many times, to spice things up, additional devices like temperature sensors, seismic detectors, or metal detectors are added to the mix.

Most times the lasers in question will be purely sensory in nature, but occasionally they are actually dangerous in and of themselves, whether through being actually harmful or deadly to touch, or through being a tripwire that sets off a bomb or something else nasty.

Invariably, the grid will not cover the target itself, leaving a comfortable alcove for the protagonist to work in, once the system has been traversed.

In reality, low-power lasers can't be seen from the side, even with CoolShades; they don't energize the air enough with photons to cause it to glow, and any laser that ''would'' give off a glow would be harmful or even deadly to touch. The aerosol trick does work on visible-frequency lasers, but if it scatters too much energy the alarm will still go off. Diverting a laser sensor with mirrors works in principle. In practice, however, it would be impossible to position the mirrors with enough precision to pull it off, or to find mirrors sufficiently flawless that they could be moved into place without their edges breaking the beam.

Furthermore, real security systems don't even use lasers. A much more reliable and accurate method for detecting intruders is a standard thermal motion detector or sonar-driven door sensor. Also, non-coherent infrared beam detectors can be used, like the kind of system in your TV remote or under your garage door, for much less money.

This is just the tip of the iceberg on hazardous hallways. For more, see DeathCourse.



* It appears an Intel ad for their I5 processor, featuring the ''WesternAnimation/{{Madagascar}}'' penguins trying to steal said processor.

[[folder:Anime & Manga]]
* DoubleSubversion in ''Manga/ZeroZeroNineOne''. The lead character does the usual tricky laser dodging maneuvers (somewhat {{justified|Trope}} in that she's a cyborg) and gets all the way through to the end. She pulls out a device to plug into the machine at the end of the hallway, uses it, then unplugs it -- and the cable falls into the laser beam, setting off the alarm. This triggers ''another'' laser grid, this one deadly, as demonstrated by cutting the wire which had tripped the alarm. The heroine tells her partner to leave her, but naturally, they escape.
* One features in the second episode of ''Anime/AngelBeats'', likely as a {{Homage}} to ''Film/ResidentEvil''. The group is trapped in a locked corridor and have to dodge the increasingly complicated laser patterns. [[spoiler:Matsushita]] ends up sliced into pieces, but of course, DeathIsCheap here and he revives soon after, although his clothes are shredded.
* The second-season episode "Cash Eye" of ''Anime/GhostInTheShellStandAloneComplex'' features a laser hallway which is quickly defeated by the Major. Her actual navigation of the hallway is portrayed in such a perfunctory way that the trope is somewhat subverted: nobody looks impressed afterward and her animated movements aren't particularly dramatic. (Her breasts are given '''far''' more artistic attention in that scene than her ability to defeat this particular laser hallway.)
* In ''LightNovel/GoshuushouSamaNinomiyaKun'', this trope is combined with [[spoiler:[[GagBoobs gag boobs]]]] to comical effect. After much careful sidestepping, the lasers eventually [[spoiler:Tsukimura Mayu's breast obscures one of the (sensory-only) beams and sets off the security response]].
* Chapter 30 of ''Manga/KaguyaSamaLoveIsWar'' opens with [[NinjaMaid Hayasaka]] dodging lasers to break into the student council room in the middle of the night and swap out [[MustHaveCaffeine Shirogane's]] personal supply of coffee beans for decaf. Why a ''high school'' of all places would have laser security isn't really specified (even if it is a school for rich kids), so it can probably be chalked up to RuleOfFunny.
* Occurred in a ''Manga/{{Kochikame}}'' TV special when one of the circus villains acrobat through the laser room which holds the gold head statue.
* Natsuki and Mai prepare to infiltrate a laser hallway in ''Anime/MaiHime'', only to discover that Mikoto has already walked into the lasers and triggered the alarms.
* ''Anime/{{Mnemosyne}}'':
** In episode one, Rin uses cigarette smoke to reveal the lasers in an [[AirVentPassageway air vent]]. She then tries to sneak through, but unfortunately [[spoiler:her butt trips the alarm]]. HilarityEnsues...immediately followed by Squick.
** In episode five, [[spoiler:Mimi]] now hides out in a Buddhist temple that comes with a "laser cage" consisting of vertical [[FrickinLaserBeams laser beams]] to trap intruders and leave them open to [[FiveRoundsRapid fire]] by her army of [[ChurchMilitant nuns with guns]]. Since it's designed to contain rather than detect, the beams are spaced at a small distance from each other.
* Averted in ''Manga/GetterRobo'': In the second episode of ''New Getter Robo'' some people pass through laser sensors that weren't visible to them ([[RuleOfPerception only to the audience from an angle where they were practically pointed at the camera]]) and were aimed in five different angles, making it so it'd be all but impossible to get past them even if you could see them.
* ''Anime/{{Pokemon}}'' features these from time to time. Team Rocket usually has some kind of [[GogglesDoSomethingUnusual special eyewear]] so they can see and evade them.

[[folder:Comic Books]]
* Parodied in ''ComicBook/AdventureTimeTheFlipSide'' when Finn, Jake, Ice King and Gunther are stealing the Lecherous Heart - after the four have done acrobatics through the lasers it's revealed that the "lasers" were normal torches held by security guards, who completely fail to react.

* The priceless diamond in ''Film/AirBud: Spikes Back'' is protected by lasers.
* The laser hallway in the ''Film/ResidentEvil'' movie where most of TheSquad is slaughtered and shredded into pieces, including one poor bastard who winds up getting "cubed." The contraption returns in ''Film/ResidentEvilExtinction''.
* ''Film/{{Cube}},'' the movie that inspired that scene, featured similar devices which sliced the characters to pieces whenever they entered a room.
* In ''Film/ExecutiveDecision'', the concept of the laser hallway is shrunk and applied to a bomb. There are two metal contacts that, if they touch, close the circuit and detonate the bomb. All around the contacts there are (unmoving) laser beams which, if interrupted, would detonate the bomb as well. One of the good guys dons what look like ordinary night vision goggles that give him the ability to see the beams, so he can hold a plastic straw in between the contacts without interrupting any of them.
* The entire plot of ''Film/{{Entrapment}}'' (1999) appears to have been constructed to provide an excuse for Creator/CatherineZetaJones to twist and bend her way through laser beams in a SpyCatsuit. According to WordOfGod, that is ''exactly'' why it was made.
* The most improbable laser hallway ever, as well as the most improbable method of moving through a laser hallway ever, appeared in ''Film/OceansTwelve'', in the lobby of a museum. Not only were there about two dozen beams, they were moving, and moreover, their movement was ''randomized'', which means there's no way to predict how and where to move through them. [[spoiler:Nonetheless, the French jewel thief extraordinaire (the Night Fox) makes it through. [[RefugeInAudacity By dancing.]]]]
* In ''Film/JayAndSilentBobStrikeBack'' the jewel thieves make their way through a laser hallway using various different acrobatics (each trying to upstage the last). They're foiled however when the last girl through ([[Series/{{Heroes}} Ali Larter by the way]]) lets one rip through her SpyCatsuit as a result of eating fast food. This sets off the audio detection alarm.
* Creator/AnneHathaway's Agent 99 navigated a laser web in the 2008 ''Film/GetSmart'' movie. The lack of a SpyCatsuit in this case was more than made up for by the presence of a slinky silver dress with a nice high split up the side. Then Agent Smart navigates it as well, though with a bit less dignity because the lasers also burn.
* ''Under Ten Flags'' (1960) had a British spy breaking the German naval codes out of a safe guarded by invisible beams (he put on infra-red goggles). Rather ironic when you realise the codes were actually obtained by the [[BoringButPractical less glamorous but methodical method]] of Ultra cryptography ([[DatedHistory still classified at the time the movie was made]]).
* Appears in the 2008 ''Film/StTrinians'' movie, which gives us just about every heist movie trope in the space of thirty minutes.
* The... [[AntiHero er, heroes]]... of ''Film/AliGIndahouse'' have to cross a room criss-crossed with lasers. Naturally they can't see the beams, so "Dave, we has to use your special powers." [[spoiler:Dave lights up his bong, takes a good strong hit, and blows the smoke out into the room]]. Once the lasers are visible, they can be avoided -- and the best way to do that of course is to [[spoiler:dance the Robot the whole way]].
* Creator/JackBlack's cxharacter navigates his way through a laser hallway in order to reach the Pick of Destiny in ''Film/TenaciousDInThePickOfDestiny''. The lasers themselves are fairly standard; however, this is probably the only example on this page that involves [[ChekhovsSkill deactivating them with the genitals]].
* A strange example in ''Franchise/StarWars Episode I: Film/ThePhantomMenace''. [[http://starwars.wikia.com/wiki/Laser_gate "Laser Gates"]] that turn on and off at intervals, but achieving the same purpose; breaking up the party so the bad guy can kill the mentor in single combat. Of course, as they were in the middle of a duel and not at all concerned about setting off alarms, there was absolutely no reason they couldn't use their lightsabers on the ''[[CuttingTheKnot emitters]].''
* An early version of this trope occurs during the robbery that opens ''Film/TheReturnOfThePinkPanther'' (1975), with the beams (columns of bright light rather than visible lasers) revealed by an aerosol spray can.
* In a tech-free variant, the bungalow shootout in ''Film/NearDark'' turns the vampires' hideout ''into'' a Sunlight Hallway, as bullet holes in the walls allow beams of skin-searing light to penetrate and crisscross the room.
* ''Film/ThePacifier'' has a laser-and-pressure-plate hallway that can only be navigated by [[ChekhovsSkill doing the goofy dance]] the DisappearedDad taught his smallest child.
* In ''Film/LupinIII2014'', Pierre demonstrates his LeParkour skills by dodging through a hallway full of lasers on his way to the MacGuffin of the opening heist.
* In the [[BatmanColdOpen opening caper]] of the 2012 Korean heist movie ''The Thieves'', a member of the gang (posing as a TwerpSweating mother) gains access to the laser-guarded vault beforehand (under the pretext of ensuring her future son-in-law has sufficient money) and leaves some chewing gum on the laser projector as she walks out. The chewing gum falls off before they've completed the theft, but fortunately the 'mother' and her 'daughter' don't have the stolen artifact on them when they're searched, having already passed it on to another member of the gang.
* ''Film/{{Screamers}}''. A lethal version protects the launch pit for the escape rocket. The protagonist has the security clearance to pass through the laser grid, but it leads to an InterestingSituationDuel when there's a last minute attempt to stop the heroes from escaping.


[[folder:Live-Action TV]]
* In a particularly JustForFun/{{egregious}} abuse of this trope, an episode of ''Series/AmericasNextTopModel'' Cycle 8 had the girls "posing" through a series of (non-harmful) lasers to compete for the chance to win a diamond necklace. [[SarcasmMode Which has so much to do with modelling...]]
* An episode of ''Series/SpacePrecinct'' had a laser trap inside a bomb. The laser was shown by firing a fire extinguisher not-directly-at the bomb in question.
* The ''Series/MythBusters'' thoroughly debunked this trope, first by discovering that visible laser security systems such as these simply don't exist (invisible infrared laser systems are sold instead), and secondly by demonstrating that even with a crude homemade mockup of the typical laser hallway most of the usual "circumvention methods" used on TV and the movies won't work, and can in fact trigger it. Specifically, they found that blowing smoke/powder at red lasers (jury-rigged from laser pointers) does make them visible, but not long or well enough to be very helpful without setting them off. Night-vision goggles plus powder make even IR beams visible, but with the same problem. Deflecting a beam with a mirror or hitting the detector with another beam worked, but was impractical. And most of their attempts assume beams placed so you could squeeze past them if only you knew where they were. Ironically, the ultrasonic motion sensors can be beaten with the ludicrous methods (tried almost on a whim by the producers) of holding up a bedsheet or simply walking at a snail's pace.
* Done rather well and "realistic" in a two-part episode of ''Series/TheSaint'', "The Fiction Makers", which first aired in December 1968 and was later released as a theatrical film. Instead of a hallway, it was a corridor between two fences.
* In the third season ''Series/{{CSINY}}'' episode "Snow Day", the lab is infiltrated by drug dealers. After capturing one of them, Mac rigs up a makeshift claymore mine to keep him in place, using a web of laser beams to bar the hallway. [[spoiler:At the end of the episode, the leader of the drug leaders dives for the machine gun that slid under the web. Mac takes cover, but the criminals ([[TrashTheSet and a sizable portion of the lab]]) go up in a massive fireball.]]
* ''Series/{{Angel}}''. Electrical-powered thief Gwen Raiden somehow bends the lasers and goes around them. In Season 5 Lindsey just walks through them using a magical glamor to prevent detection.
* An episode of the short-lived 80's TV show ''Series/TheMaster'' had John and Max have to navigate one of these.
* ''Series/DoctorWho''
** A laser hallway was used as a security measure in one episode of New Who. [[spoiler:The Doctor got through it by sonic screwdriver hacking; his force-grown cloned daughter, arriving late, had to resort to SheFu gymnastics.]]
** The Creator/TomBaker arc "City of Death" features a variation; as Count Scarlioni demonstrates how he plans to steal the [[MonaLisaSmile Mona Lisa]], he shows a holographic recreation of the famed painting in the Louvre. He shows a laser grid in front of the painting which will trigger "every alarm in Paris" if tripped. Using a device that will [[TechnoBabble "alter the refractive index of the air itself,"]] he bends the laser beams so the Mona Lisa can be removed safely.
* In ''Series/TheBigBangTheory'', the characters build such a system just for fun: they play a game, where the players have to avoid the lasers, to make a move in a chess match. Or ''[[MundaneMadeAwesome eat a slice of pizza]]''.
* In ''Series/TheCrystalMaze'', there was one game in the Future Zone (inspired from the original in ''Series/FortBoyard'') which operated on a similar principle -- using strings. Ringing a bell attached to one of the strings set off a warning. Three and it was an automatic lock-in.
* ''Series/FortBoyard'' reintroduced a laser hallway challenge in 2012... again, using strings that set off an alarm when touched. Touching about five strings appears to be enough to lock in the contestant.
* An ITV kids' game show, ''[[http://www.ukgameshows.com/page/index.php?title=Swap_Team Swap Team,]]'' featured a similar game.
* Done in the third series ''Series/RobinHood''. [[spoiler:Protecting a fake crown. With ''strings'' tripping arrows]].
* Lex's secret lab in the ''Series/{{Smallville}}'' episode "Mortal" is guarded by the deadly version. Since Clark has been BroughtDownToNormal, this is more of a problem than usual. A laser-guarded room full of priceless artifacts also makes an appearance in the season 6 episode "Arrow" - Green Arrow circumvents the (green) lasers with a crystal-tipped arrow.
* ''Series/{{Psych}}'': Shawn and Gus encountered one of these. The more limber Gus wove his way through the laser hallway and Shawn [[spoiler:just walked through, because he had already turned off the alarms]].
* ''Series/{{Chuck}}''
** In the second episode of the third season.
** They encounter another one later in the season, when Team Bartowski is sent to test a CIA security system. After Chuck demonstrates how ineffective it is, the technician replaces it with an invisible wall.
* ''Series/{{Leverage}}''
** There was an episode where Parker was trapped by a laser grid akin to the one in ''Film/OceansTwelve''. She navigated it by doing ''cartwheels''. It is unknown if she tripped any of them, as they meant to trigger the alarm anyway.
** In a flashback in one episode, a teenage Parker is shown doing something similar to get to an ice cream sundae as part of her training. Her mentor then holds up a spoon, and she presumably does the entire thing backwards without spilling the ice cream, although it cuts back to the present before we can see her try. The same spoon shows up earlier in the episode, in a shot of her apartment / supply cache, so she did.
** Parker has also overcome a roomful of lasers before using tinfoil, ice and chewing gum.
* In ''Film/ItsAVeryMerryMuppetChristmasMovie'', Fozzie Bear, while trying to deliver a bag of money to the bank, is nearly prevented by doing so by the evil owner of the bank by one of these. Instead of actually triggering an alarm, these lasers are military-esque grade weaponry, which '''burn''' anything they come into contact with. In a true CrowningMomentOfAwesome for any Muppet film, Fozzie Bear ''runs through the burning lasers'', just to realize he forgot the bag. [[BlackComedy Painful]] HilarityEnsues, as he manages to run through them again and back.
* Phoebe and Piper of ''Series/{{Charmed}}'' had to steal a chalice from a museum. The chalice was in a room with moving lasers. So, Piper froze the lasers and Phoebe maneuvered through the openings.
* ''Series/FightScience'' employed a non-moving visible laser hallway to demonstrate a female ninja's flexibility and kinesthetic sense. [[http://channel.nationalgeographic.com/series/fight-science#tab-Videos/07741_00 She clears the room in 56 seconds and does a back walkover out of the room just to show off]].
* The ''Series/BionicWoman'' remake had them visible despite the fact that Jaime's bionic eye [[JustifiedTrope could have given her a plausible way]] of seeing infra-red beams. Subverted when instead of trying to slip through the beams, her partner deliberately steps into them so they can get captured as a TrojanPrisoner.
* In ''Series/KickinIt'', there's one outside the mall security office(!), Then the door itself is unlocked and the safe has an easily guessed 3-digit code.
* Variant in the ''Series/BabylonFive'' episode "A Voice In the Wilderness, Part 1", perhaps counting as an inversion; the lasers don't set off an alarm or a trap; rather, an unseen sensor of some kind sets off a series of death lasers (or some other form of visible {{Death Ray}}s) in a hallway.
--> '''Ivanova:''' [[DeadpanSnarker Well, that'll cut back on tourism]].
* In the episode [[Recap/SupernaturalS02E19FolsomPrisonBlues "Folsom Prison Blues" (S02, Ep19)]] of ''Series/{{Supernatural}}'', the Winchesters trigger a motion detector in the museum.
* In one of the funniest moments in ''Series/AgentsOfSHIELD'', May and Coulson encounter one. Just as Coulson stretches and limbers up to dodge his way around them to the control panel on the other side, [[CuttingTheKnot May rolls her eyes and just walks right through, setting off the alarm]].
-->'''May:''' They already know we're here.\\
'''Coulson:''' Oh. Right.
* In the ''Series/NCISLosAngeles'' episode "Deliverance," [[ActionGirl Kensi]] is kidnapped and held in a room full of lasers; breaking one of the beams will set off a bomb. Fortunately, [[CrouchingMoronHiddenBadass Deeks]] has a laser of his own which he uses to fool the laser sensors so Kensi can escape.
* In a second season episode of ''Series/TheFlash2014'', Captain Cold has to pass one of these to pull off a [[TheCaper diamond heist]]. Not only are the lasers 100% visible, but he is able to use his [[AnIcePerson cold gun]] to ''[[ArtisticLicensePhysics freeze them solid and shatter them]]''.
* ''Series/{{NTSFSDSUV}}'': Parodied when the team has to break into the NTSF database mainframe, which is protected by a single laser beam. Piper changes into a SpyCatsuit and does a full minute of gyrations and stripper poses around the laser before she gets past it (clearly parodying ''Film/{{Entrapment}}'' in particular). Her two colleagues just casually hop over it with one step.
* ''Series/MacGyver1985'': Mac had to negotiate his was past the deadly version in "Pilot"; and the detector version in "The Heist".
* ''Series/WonderWoman'': Perhaps due to airing during the era of the first Franchise/StarWars movie, Wonder Woman started facing various laser weapons, including a hallway in "I.R.A.C. Is Missing".

[[folder:Music Videos]]
* In the music video for Britney Spears' "Toxic", stealing the vial of Mysterious Green Stuff sets off one final trap to get through: a hallway of rotating laser beams that she must dance through.
* Music/LindseyStirling's [[http://www.youtube.com/watch?v=9p0BqUcQ7i0 collaboration with The Piano Guys]] on the ''Series/MissionImpossible'' theme parodies this trope. The red lasers contrast with a predominantly black-and-white video. Lindsey carefully moves around and under the beams while playing the violin, but the cellist simply [[SubvertedTrope turns off the alarm system to walk through]].

[[folder:Tabletop Games]]
* ''TabletopGame/{{Shadowrun}}''. ''The Neo-Anarchists' Guide to Real Life'' gives information on this defense system and how to defeat one, including setting up a network of mirrors to create a safe passageway through it.
* Heritage Games' ''Star Trek: Adventure Gaming in the Final Frontier'', adventure "The Slaver Ruins". One corridor is protected by FrickinLaserBeams that will damage anyone they hit as if shot with a laser rifle.

[[folder: Toys]]
* The game Chrono Bomb makes a sport of this trope: touch-sensitive plastic strands are strung across a hallway as "lasers", so kids can try to duck and weave their way to a plastic "bomb" without making contact before the timer runs down.

[[folder:Video Games]]
* ''VideoGame/BeyondGoodAndEvil'' loves these. In fact, when you're not avoiding being seen by guards, you're dodging laser beams. Or both, at the same time.
* In the ''VideoGame/{{Crusader}}'' games, invisible lasers appear every once in a while that trigger all sorts of nasty business if the player walks through them. The emitters, however, are visible, albeit very tiny, and can be blown up.
* Appears in ''VideoGame/DeusEx'' and the sequel ''[[VideoGame/DeusExInvisibleWar Invisible War]]''. Often appears without holes, but it does tell the player to find a solution.
** In the original, red beams trigger alarms (which in turn activate any turrets in the area) while blue beams trigger something else...sometimes trivial sometimes instantly lethal. EMP devices are temporarily effective.
** In the sequel, blue is replaced with white (and only shows up once) while green shows up to trigger gas traps and gold beams are weapons themselves.\\
The NPC that tells you these useful tips also mentions that the light is holographic to scare away intruders, while the beams are invisible. While some uses of this warning are justified, more than a few times the bad guys would have done better to turn off the holographs. Still, the writers did their homework enough to handwave.\\
A better use of holographic beams springs easily to mind - put them somewhere ''other'' ''than'' (though perhaps near) where the invisible operational beams are.
** A "Resident Evil room" (The developers call it that and a poster for it appears a room or so back) appears in ''VideoGame/TheNamelessMod'' as part of the labyrinth created by the insane Shadowcode. Interestingly enough, the lasers are triggered ''only'' by your body. You don't even need a mirror - just take a box and block the beam, creating a safe passageway. Huh.
** A large room full of lasers is in ''Human Revolution''.
* ''VideoGame/MetalGearSolid2SonsOfLiberty'' has laser hallways rigged to explosives. They actually are invisible unless you use the IR goggles or plain old cigarette smoke. Only one can be crawled through. The rest require you to find and shoot their control systems.
* Lasers also appear in the original ''VideoGame/MetalGearSolid'' and the Gameboy version as well. They trigger an alert when broken (or in one case in MGS, [[GasChamber flood the area with poison gas]]).
* ''VideoGame/{{Psychonauts}}'' has a laser tunnel in the Lungfishopolis level.
* ''VideoGame/QuakeII'' has ''many'' such traps, and in one instance as the Marine attempts the jumping puzzle, guards hidden in alcoves in the walls appear to take shots at him. One in the start of the third hub can be circumvented via an alternate route.
* In ''VideoGame/QuakeIV'' there is a mid-game level in which Kane comes across a few space marines near a laser hallway. The marines point out that the lasers are deadly, as discovered by one of them who foolishly thought he could dance his way through. Subverted for the player in that the tech among them points out that the lasers seem to be scanning for Strogg DNA, and Kane, having been stroggified and having the adequate physiology, can pass through unharmed. Later on, he disables the lasers and rejoins with the squad.
* In ''VideoGame/ResidentEvil4'', Leon has to dodge through a laser hallway about halfway through the game -- which is actually a nod to the movie. This happens again in ''VideoGame/ResidentEvilTheUmbrellaChronicles'' when Chris and Jill infiltrate an Umbrella base at the end of the game. Another one in ''VideoGame/ResidentEvil5'' incorporates a LightAndMirrorsPuzzle.
* ''VideoGame/{{Persona 2}}'': If you mention the Laser Trap in [[spoiler:Xibalba]] first, that's what you'll encounter. You will encounter it later anyway even if you didn't choose it.
* ''VideoGame/SlyCooperAndTheThieviusRaccoonus'' had tons of these scattered throughout. Initially sensory, they would switch over to weapons-grade lasers if they detected intrusion. They were, in all cases, visible from any angle without any need to apply phlebotinum. A Making Of video in the third game showed beta footage of Sly using a spray can of some sort to use in order to see invisible lasers within a maze.
* ''VideoGame/{{Oni}}'' is chock full of moving laser bars. Two end bosses are massive cybernetic brains who use a rotating pattern of laser beams against the player. The bosses are inert until the beams are crossed, then they unleash some impressive firepower at the player (who they don't seem to otherwise even ''see''). At several places, there are large obstacles behind which the player can hide to avoid being intercepted by the lasers... and which also hold the terminals to disable the boss. They are situated ''inside the boss chamber''.
* In the adventure game ''Koala Lumpur: Journey to the Edge'', one puzzle involves navigating three laser-beamed hallways. Each one has a distinct pattern (a clue at the entrance of each reveals it). The FridgeLogic nature of this setup is somewhat mitigated by the fact that it's on board a space station in an alternate universe, and that the station is owned by a child genius who might have just been going with the RuleOfCool rather than the best possible security system.
* ''VideoGame/UnrealIITheAwakening'' has a hallway with blue killer laser complete with audio cues.
* ''VideoGame/{{Robotrek}}'' has lasers in an enemy base which activate/deactivate in a pattern. They're invisible unless you're wearing a pair of special goggles. Tripping a beam activates an alarm that brings enemy troops running into the room.
* ''VideoGame/MegaMan2'' has Quick Man's...pretty much the entire level. Here, though, the laser beams are huge and kill you if you so much as touch them. You will also see them in ''VideoGame/MegaManX5'' as a shout out.
* ''VideoGame/IWannaBeTheGuy'' has a room that pays homage to the ''Mega Man'' level.
* Ring Man's level in ''VideoGame/Rockman4MinusInfinity'' has 2 sections filled with laser beams. Fortunately, they are not {{one hit kill}}s.
* ''Franchise/SonicTheHedgehog'':
** ''VideoGame/SonicAdventure2'' had a bunch of these, mostly in vertical passages of shooting levels, but also notably in Security Hall.
** ''VideoGame/ShadowTheHedgehog'' had some also, though these were usually just beams and could be defeated by pulling a block out of the wall with the vacuum gun to block the laser. In one case, you have to pull two blocks out, one on each side of the passage you're trying to get through.
** Also appears in a number of levels in ''VideoGame/SonicHeroes''. The most notable level is [[BigBoosHaunt Mystic Mansion]], where Team Chaotix have to destroy a ring-stealing robot and then hit a switch ([[NintendoHard which has several lasers touching it, and it's very small]]) in order to reach the rest of the level. Oddly, the other teams don't have to deal with this room and the one before it, and one of the characters on that team (Espio the Chameleon) can turn invisible...and when he does, most lasers don't hurt him. The only ones that do are in Final Fortress, and they're huge and very different from the small red ones you usually see (they're even different colors, and they fire at you instead of being the classic grid!).
* Amusingly subverted in ''VideoGame/{{Fallout 3}}''. The Enclave fortress doesn't have the traditional laser beam corridors, but it does have anti-vermin laser traps under the various passageways. If the player crosses them, a weak flamethrower is ignited. They are utterly ineffective against the player at that point, and not only can they be avoided by simply going fast -- the player needn't even bother with them to exit the level.
** Played straight in ''VideoGame/{{Fallout 4}}''. If you don`t have the right lockpicking perks to bypass it, you have to go through a laser beam corridor to obtain the "Treasure of Jamaica Plain." If you trip a laser beam, [[MoreDakka several machine gun turrets immediately open fire on you]]. Assuming you painstakingly disable every single laser beam without getting filled with bullets, you can finally get your hands on the treasure...[[spoiler:a time capsule filled with mundane pre-War items]]. The ''Automatron'' DLC has a laser hallway in the Mechanist's stronghold, which you can either short out with the decontamination sprinklers, or bypass by picking an Expert-locked door.
* ''VideoGame/WinBack'' for the N64 has all sorts of horrible death lasers set up everywhere...including among the a.c. vents on the top of the main building. Not really explained how or why they were put there...but funny when the enemy freaks out and runs straight into one. Thankfully they move slowly enough Jean-Luc (yes, really) can somersault past. The blue variants don't kill immediately, but alert enemies or activate other traps.
* ''VideoGame/GearsOfWar 2'' has a laser hallway with instant-kill flamethrowers. One person must turn them off in sequence (only one can be off at a time) to allow the other to run the gauntlet.
* ''VideoGame/NoOneLivesForever'' includes a serious of laser hallways, leading up to a completely impassable one...where Cate simply [[AirVentPassageway yanks open a floorboard and goes under it.]]
* The ''VideoGame/MetroidPrimeTrilogy'' features some Morph Ball tunnels with lasers, hallways with [[EyeBeam eye-like structures that shoot lasers]] in the [[VideoGame/MetroidPrime first game]], and in ''VideoGame/MetroidPrime2Echoes'', a regular laser hallway (though with not many lasers). ''VideoGame/MetroidPrime3Corruption'' has a single corridor wired with invisible lasers, designed to teach the player to use their shiny new X-ray visor to look for traps like this.
* Shows up in ''VideoGame/HalfLife'' in two forms (both visible): blue for laser tripmines, and red for turrets. On a notable instance in ''VideoGame/HalfLife1'', a missile warehouse is crisscrossed with lasers from tripmines planted ''everywhere'', to the point where tripping one single mine will [[GameOver toss the whole building up in smoke]].
** Naturally enough, several show up in ''VideoGame/HalfLife2'', including a number of turret-activating tripwires in the Overwatch Nexus that culminate in a room full of dozens of the things. (If you trip one, [[UnwinnableByDesign the doors slam shut and the indestructible turrets ventilate you]].)
** There's also an examine in ''Episode 1'' where your AirVentEscape collapses beneath you, trapping you in a room full of tripmines, hopper mines, and exploding barrels. The developer commentary lampshades the fact that the room makes no sense whatsoever, but [[RuleOfFun it's fun]].
* There is actually a laser hallway in ''VideoGame/{{Zork}} III,'' yet another of the series' numerous anachronisms.
* ''VideoGame/SpaceQuest IV'' has one of these; you have to use cigarette smoke to see the lasers so you can adjust them to let you pass safely.
** The first game had a laser fence that you had to disable by reflecting the beams with a piece of glass.
* Lampshaded in ''VideoGame/TheSims2'', if the Sim works in the criminal career and steals a diamond protected by a laser field with convenient gaps. The Sim in question is even said to wonder aloud why no one simply uses a solid laser wall.
* The inexplicably [[MadeOfExplodium explosive]] lasers in ''VideoGame/ConkersBadFurDay''.
* ''VideoGame/TheArtOfTheft'' makes a gameplay mechanic of these lasers.
* Permutations of this pop up in the ''Franchise/RatchetAndClank'' series.
** By ''Tools of Destruction'', the titular duo starts mocking their inclusion.
** In ''VideoGame/SecretAgentClank'', the first UnexpectedGameplayChange to RhythmGame is in a particularly mean laser hallway.
* The alarm type appears in ''VideoGame/VampireTheMasqueradeBloodlines'' at the end of one level. The visibility can be justified by the player being a vampire with super senses, the fact that they are arranged so that they can be crouched under or jumped over can't.
** The deadly type appears later on. Justified in their impracticality as being specifically designed to test the survival skills of vampires.
* ''VideoGame/DukeNukem3D'' has the Laser Trip Mine.
* Some hallways in ''VideoGame/SecondSight'' are blocked by a laser grid. In order to get past it, you have to use the astral projection power, as your "ghost" can move through these barriers but not through physical objects.
* ''VideoGame/PerfectDark'' had a laser hallway in an early level that could only be circumvented by waiting for a maintenance robot to pass though and temporarily deactivate it. A later level has a huge laser grid surrounding Air Force One that required you to find a way around it.
* In Creator/TelltaleGames' ''VideoGame/HectorBadgeOfCarnage'' you break into the backroom of a sex shop only to find one of those in your path. You get through it by [[spoiler:flipping the switch located right by the entrance to turn off the lasers]]. Hector is way too fat to squeeze through the gaps in the laser grid.
* ''VideoGame/MissionImpossible1997'' has you descend through a laser grid to reach a computer terminal, just like in the [[Film/MissionImpossible first movie]].
* ''VideoGame/{{PN 03}}'' has a number of standard laser hallways, as well as WaveMotionGun-caliber [[OneHitKill death beams]].
* The ''VideoGame/CityOfHeroes'' "Casino Heist" Summer Event mission, being based on the tropes of TheCaper, has one of these.
* A few instances in ''VideoGame/{{Penumbra}}'' appear in some varied forms.
** Black Plague features explosive packs wired to lasers that trip if the player walks through. They can be disabled by a small puzzle or switches.
** Requiem is more of a hallucinatory type. Malfunctioning blue lasers in one area, while harmless to Philip, cause the ball required in a puzzle to teleport back to the start. And later is a ring of red lasers that disintegrate anything on contact - it's even resistant to any object held towards it.
* As a potential {{shoutout}} to [[VideoGame/MegaMan2 Quick Man's stage]], ''VideoGame/TheAngryVideoGameNerdAdventures'' has timed instant-death rays in the "Future Fuckballs 2010" and "Laughin' Jokin' Numbnuts" stages.
* Orokin towers in ''VideoGame/{{Warframe}}'' have the weaponized variety in ''spades'', ranging from stationary to rotating to vertically/horizontally sliding. These energy beams ''will'' murder anything that stands in them for more than half a second or so. Fortunately, the emitters can generally be destroyed from a distance. The towers often contain challenge rooms that combine lasers with timed doors and motion-slowing patches on the floor; {{Parkour}} skills are required to reach the end in time and collect the rare equipment contained within.
* ''Videogame/SyphonFilter: Dark Mirror'' has laser trip mines whose beams are invisible except with the infrared or EDSU goggles.
* ''VideoGame/{{Antichamber}}'' has lasers that trigger various things, usually doors. Normally they are beneficial, but a few puzzles involve blocking them by putting blocks in the way. At least one makes a grid that covers the entire corridor.
* In ''VideoGame/OriAndTheBlindForest'', [[VideoGame/MegaMan2 Quickman]]-style insta-death lasers are a common trap. Some flash on and off, creating a CorridorCubbyholeRun situation, others are constantly on and need to be blocked with an object, and others oscillate or rotate.
* ''VideoGame/TombRaiderTheAngelOfDarkness'' has one in the Louvre. Mind you, the game was released before ''Film/OceansTwelve''.
* A miniaturised, [[DeconstructedTrope more plausible]] version of this appears in the Museum track of ''VideoGame/ReVolt'', triggering an alarm in the background as cars pass through it.
* The remake of ''VideoGame/{{Flashback}}'' has laser gates that instantly vaporize Conrad if touched while active. One hallway on Earth requires you to pass through a series of blinking lasers while a moving laser is [[AdvancingWallOfDoom advancing behind you]].
* Defied in ''VideoGame/SaintsRow4'' during the mission "The Mysterious Case of Mr. X," a parody of various stealth games.
-->'''The Boss:''' And this is the part where we have to turn back, right?\\
'''Asha:''' I hope you're limber, even the slightest disruption of a single beam will send a 2000-volt shock through your body. What we'll have to do is move through the gaps in a serpentine pattern.\\
'''The Boss:''' You have fun with that, I'm taking the [[AirVentPassageway air vent.]]

[[folder:Web Comics]]
* A [[http://wapsisquare.com/comic/11082002/ one shot]] gag in ''Webcomic/WapsiSquare'' shows that apparently there are a few lasers involved in the museum's security system.
* Cyborg girl Monty (an OC fanfic character of the ''Manga/GunslingerGirl'' manga) [[http://wraith11.deviantart.com/art/JM-Issue05-05-244267815 dodges the security system in a French casino robbery]].
* Geist from ''Webcomic/{{Heist}}'' does one of these in the first issue. He happens to be an {{invisib|ility}}le [[{{Intangibility}} phase-shifter]] so it was a lot easier for him than most characters.
* ''Webcomic/{{Sinfest}}'': [[http://www.sinfest.net/archive_page.php?comicID=3190 Part of the vault security.]]

[[folder:Web Original]]
* The WebAnimation/StrongBadEmail ''[[http://www.homestarrunner.com/sbemail178.html Bike Thief]]'' features a laser hallway that's more of a Laser Couch.
* Appeared in a ''WebVideo/{{lonelygirl15}}'' video, of all places; in "Mission Possible", Danielbeast has to navigate one of these.\\
* Lampshaded in ''Machinima/FreemansMind'' while trying to navigate a room with tripmines placed on possibly every available surface, right near a couple of missiles already stored in the room. He also is confused as to why all lasers are visible in Black Mesa.

[[folder:Western Animation]]
* Trevor Goodchild uses one on ''WesternAnimation/AeonFlux'' in the first episode of the TV series. It's suggested he knows the problems with this setup, he just likes to watch the gymnastics she does to get out of it.
* This has been seen at least twice on ''WesternAnimation/TheBackyardigans''.
* ''WesternAnimation/BatmanTheAnimatedSeries''
** In her first appearance, Catwoman uses a clever way of getting past such a hallway (actually, a room) to steal a diamond necklace; she uses her housecat Isis - who can ''see'' the infrared beams and, thus, can steer around them with her sleek body - to get the jewelry for her.
** Harley Quinn simply jumps around the beams when she goes to steal a diamond. Works fine, but then Ivy activates the alarm during her own robbery from another wing of the facility.
* In ''WesternAnimation/CodeLyoko'', Yumi encounters once a laser hallway of the deadly variety in Sector 5. Good thing she's the most acrobatic of the team.
* The closing credits of ''[[WesternAnimation/{{COPS}} C.O.P.S.]]'' had Nightshade navigating one wearing special goggles in order to see the lasers.
* Parodied in a ''WesternAnimation/DextersLaboratory'' episode where Dexter just walks under the lasers ([[MundaneMadeAwesome in a library, close to the devolution box!]]) since he's really short.
* In the ''WesternAnimation/DuckTales1987'' episode "Dime Enough for Luck", Magica De Spell tricks Gladstone Gander into stealing Scrooge's Number One Dime. The dime is guarded by an impressive set of moving lasers that he bypasses because he has unusually good luck.
** ''WesternAnimation/DuckTalesTheMovieTreasureOfTheLostLamp'' featured Huey, Dewey, Louie and Webby having to go through one of these in Scrooge's office building. One difference from other example: those lasers are ''lethal''.
* The episode "Double Date" from ''WesternAnimation/JusticeLeague Unlimited'' sees Huntress use an aerosol spray to reveal lasers in Mandragora's home. She simply vaults and flips through them.
* These show up all the time in ''WesternAnimation/KimPossible''.
** Drakken even has a laser snow field around one of his lairs.
** The best one is from "A Sitch In Time", where the entire room is filled with deadly laser beams, and Kim gets her first job: using her cheerleading and gymnastics moves to dive through all the beams and turn it off. She was looking for jobs like babysitting.
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "Mmmystery On The Friendship Express", while trying to figure out who vandalized the cake, [[{{Cloudcuckoolander}} Pinkie Pie]] imagines that [[Franchise/JamesBond Con Mane]] infiltrated the place, revealed the laser beams with a spray, then used a mirror to bounce them onto the cake. Annoyed, Twilight Sparkle points out, "Pinkie! There is no laser beam security system!"
* Parodied in an episode of ''WesternAnimation/OzzyAndDrix''. Drix and Maria encounter a laser hallway blocking the entrance to "The Fear Center". Drix gets through it by squeezing between every laser as carefully yet clumsily he can. After he's done, Maria, who is a cop, simply pulls out her ID card and deactivates the lasers.
* Doctor Doofenschmirtz installs an "anti-platypus security" system in one episode of ''WesternAnimation/PhineasAndFerb'' that includes a laser hallway, among other traps. Naturally, Perry manages to avoid every trap easily.
* In ''WesternAnimation/ThePowerpuffGirls'' episode "Cat Man Do" a cat hypnotizes the Professor and the two go to the museum to steal the Cat's Eye Jewel. The Professor puts a container of grease on the floor and slides the cat under the lowest beam, leaving a trail of grease behind. The Professor then does the same and they steal the jewel.
* The early Kids' WB toon ''WesternAnimation/RoadRovers'' did a variant on this in an ep titled [[http://members.tripod.com/~RRStuff/epguild.htm#EP7 Hunter's Heroes]], replete with mirror deflection. (The website linked from this entry also acknowledges the difficulty on [[http://members.tripod.com/~RRStuff/gallery.htm this page]] [see "Deflector"].)
* In ''WesternAnimation/TheSpectacularSpiderMan'' one of these appears, somewhat [[WhereDoesHeGetAllThoseWonderfulToys peculiarly]], in the genetics labs at Empire State University, to deter theft of the "ooze." This doesn't stop the ComicBook/BlackCat from trying, however.
* In the ''WesternAnimation/SWATKats'' episode "The Dark Side of the SWAT Kats", our heroes (and their [[EvilCounterpart Evil Counterparts]]) have to jump through one of these to break into Pumadyne Weapons Lab.
* Robin and Red X both overcome a tangle of lasers that are protecting a Xenothium vault when Robin goes after whoever was in the Red X suit in ''WesternAnimation/TeenTitans''. Earlier, Red X dealt with a laser at ankle height by simply placing a mirror in its path, reflecting the beam upward.
* Used in the second ''[[WesternAnimation/TeenageMutantNinjaTurtles2003 Teenage Mutant Ninja Turtles]]'' toon, where April, Casey and Splinter are forced to traverse one of these in order to rescue the turtles in an early season 3 episode. While it proves easy enough for Splinter and April (who in this episode reveals that she has [[TookALevelInBadass taken a level in badass]]) it proves quite difficult to the graceless Casey.
* Used three times in the challenge of ''WesternAnimation/TotalDrama''. In the episode "Dial M for Merger" (Action), "Can't Help Falling In Louvre" (World Tour) and "Scarlett Fever" (Pahkitew Island).
* In ''WesternAnimation/TransformersAnimated'', it isn't so much a hallway, but the Autobot's base is filled with motion sensors. In "Home Is Where The Spark Is", they sense movements and grab the Autobots.
* On ''WesternAnimation/UncleGrandpa'', Uncle Grandpa and company end up accidentally breaking into a bank vault scattered with lasers while looking for a treasure. They end thinking it's a ''dance rave''.
* Used and mocked in ''WesternAnimation/TheVentureBrothers'' when Doctor Girlfriend and Henchmen 21 try to go to the Monarch after Dr. Killenger becomes his new right hand man. A hallway has laser tripwires, and Doctor Girlfriend nimbly flips and weaves through them all. Henchmen 21 tries, and just trips into a lot of them from the start setting off an alarm (nothing deadly, just sirens). Doctor Girlfriend then just opens a secret hallway to where the Monarch is and leaves 21 behind.
* In the ''Franchise/WallaceAndGromit'' short ''WesternAnimation/TheWrongTrousers'', Feather [=McGraw's=] plan for bypassing the lasers protecting a diamond is by having a sleeping Wallace, strapped to remote-controlled Techno-Trousers, walk on the ''ceiling'', then using a retractable arm on Wallace's helmet to snatch the gem. It almost works, until the arm swings over and the diamond hits one of the lasers, activating the alarm.
* In the first episode of the '90s ''WesternAnimation/XMen'' series, the beams are detected by smelling ozone, revealed by super-summoned fog, and shut down by scaling overhanging pipes to reach the control panel.
* In ''WesternAnimation/XMenEvolution,'' Iceman uses an ice bridge to pass the beams along the floor, and when bragging to Shadowcat, he's spinning the keys (to disable the security system) on his finger. They fly off, fall through a beam, and trigger the alarm. The look on Iceman's face is priceless.

[[folder: Real Life]]
* There's a "laser maze" game at the Excaliber casino's arcade in UsefulNotes/LasVegas.
* The British Museum uses a "beam system" to protect some of its exhibits. However, given that they're not protected in any other way, nobody bats an eyelid when someone sets off the alarm (since it can be easily done innocently by someone who's leaning in to get a closer look), and the "beam system" gets a sign to itself... [[RuleOfCool it's probably not there because it's effective]].
