- Those laser pointers you can buy at the store actually pack some pretty powerful technology, and a recent study shows most manufacturers are actually jacking up their pointers' power output to illegal levels- meaning some consumer pointers have the ability to burn retinas and skin and blind airline pilots!

"Those handheld green lasers pointers may not be as harmless as you thought."
"NIST Tests Underscore Potential Hazards of Green Laser Pointers"
www.nist.gov/pm...
"Using a low-cost apparatus designed to quickly and accurately measure the properties of handheld laser devices, National Institute of Standards and Technology (NIST) researchers tested 122 laser pointers and found that nearly 90 percent of green pointers and about 44 percent of red pointers tested were out of compliance with federal safety regulations. The NIST test apparatus was designed so that it can be replicated easily by other institutions."

Blinding pilots? My 900000000wm laser just cuts the plane in half
South Will Rise Again Mw, not wm. Mw is a milliwatt, or one one thousandth of a watt. Yes. 1/1000th OF a watt.
So, a 100Mw laser is 1/10th of a watt. It doesn't take much to make a powerful laser. A 100 Watt laser could cut steel.
A 1000 watt unit could cut steel at a distance. This is a highly organized and concentrated beam of photons at one specific wavelength.
It's mw not Mw . Capital M is for mega , lower case m is for milli
No matter how stupid it sounds it's still funny
Good one ;)
+Michael Echeverria At least 200mV lazor pointer can burn a pilot's eye. This caused the recent emergency landing at Heathrow. I also and always support the South. Cofederates Banzai!
GOD it's fun I just busted the planes tail
I shine my into people's house and piss them off 😂
me to
+Furious Gaming 😂😂
+Shiraz McClennon I know 😂
+TrippyPlays how? don't they see where its coming from? like dont they see the beam?
Same!! ;)
It's just fascinating to see this beam of light traveling through the night's skies. Especially when it's foggy. That s when u can see it better
+Andrei Bondoc but then you never know what behind them clouds and the dark it might be planes and you get yo ass in trouble!
no it can't go that far, it's not a super high precision laser genius
+Andrei Bondoc
Also, no one seems to mention this, but how the hell can you blind a pilot from the ground mid flight? I mean the cockpit isn't on the bottom of the plane. It seems you could only do such a thing near landing and takeoff and in the states that means you are also near an airport which aren't generally full of places for dopes with green lasers to loiter. I actually don't believe that thousands of people are arrested every year for this offense.
+DvidTheGnome well there's cases when pilots were blinded or disturbed by the laser beam. Put it like this. They can see the houses from up there, so a light beam can come through from those houses. The laser beam is a really compact strong light. The. Powerful ones release heat when they hit an object
+Andrei Bondoc
If you look it up it's basically confined to gangbangers flashing police helicopters and the odd news copter getting hit by some drunk idiot. This is not what this video implied, like not even close. I would actually say this is a completely disingenuous video from discovery or whatever old meets new media this channel is. The question is why though? Is there some reason 99.9% of people need to know (and in a completely deceptive spin type manner) that they will get the book thrown at them if they do something they are clearly not doing. This whole thing comes across less like news, but a sort of preemptive conditioning through spin. Maybe they have some sort of really sensitive new microwave technology, or theres a lot of particulate in the air for bouncing satellite feeds in some more advanced manner. Who knows. All I got from this video is that it's important not to shine lasers in the sky, but ultimately the reason for this remains unclear, as the stated reason simply doesn't hold water.
66mW LOL, He hasnt seen my videos xD
Your videos rule
Thats what Im saying! I bet he hasn't seen a 1W before
lol i know, this guy needs to learn a little more about lasers
juniortore1 I got an arctic spider three 2W laser
Nice
My cat goes mental over my laser pointer. Like........mental......
By mental I mean every once in a while you have to stop otherwise he'll exhaust himself trying to catch the thing. He has no self control xDD. You'll stop and he'll be staggering and panting like a fat man.
maybe your laser poiinter drove your cat to insanity :)
Mine is on it's way from eBay
Marty Party2809 which one you order????
I had a green 1w laser super powerful I would use it to point at stars and amazing people . I used it alright I sold it for drugs and got high
i have a blue 1w.. its pretty fun to use! you can light a bowl or a joint with it too... lol
+Q StiX lol I know
Justin Dir looks like we all know
Hahahaha lol
Justin Dir lMFAO
Which will win?
1. A complex flying machine with millions of dollars of research behind it?
2. A small shiny boi?
A shiny boi😂
I use a lazer two point at my wall and move it to dofferent places
IM LOOKING FOR A GREEN LASER PEN BUT IDK WHERE TO BUY ONE CAN I GET SOME HELP?PLEZ?I DONT WANT A BURNING LASER I WAT A NORMAL LASER?
Hollywood California just get the lazer like mine just search on ebay Lazer point green not burning
***** OK THX
Hollywood California caps lock... really
SO DO U CARE? NO RIGHT.EXACTLY.JK BUT yeah *****
So my question.. how the FUCK did they find the guy who shined at the plane? :)
+Notorious toast preferably the latter cause they're the real crims.
+Jimmy Andersson Heli, Police, etc..
well if it blinded the pilot then you can just watch the trail and see where it came from :)
They help when your trying to show someone where you need something done like mounting some lights or running wires also in landscaping very helpful to point out future fence lines and anything else your imagining in your head and need to visualize it for someone
I had a home-made laser pointer before they were common and well-known. It was assembled in a cardboard mailing tube a couple inches in diameter, most of which was taken up by the primitive switching power supply to produce thousands of volts from flashlight batteries.
I have a 1W (1000mW) 445nm blue laser. It burns stuff and will blind people. But when I enjoy burning my name on a piece of wood with laser goggles on that shouldn't be a problem.
The intro 😂🤣🤣
Things I use my laser pointer for: Messing with my pets, Underlining text and Pointing at things to show other people
'It's not my fault the pilot didn't wear safety goggles! Make them use safety goggles! Mandatory!' LOL...
i had this amaizingly strong lazer pointer at one point that was green... i pointed it at a mountian from the base, and i saw it, about 3 miles away!
I use my laser pointer to mess with teachers at school
AJGamesHD me too lol, I hide it in my fist xD
J-Tech lol
I use my 30mW green laser for checking for snowfall at night. Every flake that comes down sparkles as it goes through the beam. Beautiful. Also used to point out star constellations.
Just got a XY-laser 303 and I just point at stuff and see how far it will go but I am carful.
cant wait to blind some pilots .
waiting for shipment to arrive
I run around at night with my friends shooting them I'm people's windows
i get on my roof and point it at a group of pedestrians. every so often i hear "Sniper! Get down!"
Okay, first of all, I completely agree with all of this guys statements. People shouldn't be doing things that they are doing with laser pointers. Second of all, they are not illegal, at least in new york state they aren't. This is how I know. I was with my friend and he lives near a factory type thing and we were shining it on the workers wearing reflective jackets and they would glow up all green. Turns out they called the cops, thinking it was some sort of gun, and the cops eventually found us and asked me a few questions. I showed him my laser and he was suprised to know that I had it. After about 10 minutes, he let us go with a warning, that's when I asked him if it was illegal. He told me that it's okay to shine it on bilboards or something and not at people. He said that it was legal to have, but it depense on if you do something stupid. What im trying to say is that laser pointers are not illegal themselves. It's only what you do with it is illegal.
laser pointers also amuse some dogs... not just for cats...
My dog is scared of my laser.
I have A green one that is 200MW... I love it :)
+Marcus Campbell Damn you have a good one I have a 5 MW
+Bilbo Bagens Thanks! Me and my friends ride around messing with people. It's hilarious 😂
+Marcus Campbell I have 700mw 532nm (green)
+Marcus Campbell I've seen a 7w. serious piece of equipment.
+Lewis Blake Cool! You're exactly right, powerful little tool
The only thing these lasers are good for is permanently blinding cute kittens.
i actually... shine outside to see the awesome green beam in the dark
I use my lasor pointer to prank people
laser*
It's the Chinese who are overspecc'ing the lasers and lying about output, not American companies.
Are you sure? there is a site "wickedlasers" . A 900mW+ green laser is like 1000$ and I just bought one green laser 8000mW = 8W for 10$. I live in Romania if you wonder
+InF3cTu9 8W green just doesn't exist, and even several hundred mW is usually $200 at a minimum. That's because green needs two crystals while others need zero. In green, they need to take 808 nm and with Nd:YAG crystal convert it into 1064 nm. Then 1064 nm is converted into 532 nm with an expensive LBO or BBO crystal. You need about 5W of IR light to make 1W of green light, if (if it existed) 40W IR to make 8W green.
+InF3cTu9 That would put out so much heat that you would need a water bath inside your laser. It would require so many batteries that you couldn't fit them into a tube. Not being mean, just letting you know the costs and difficulties of going that high.
baguazhang2 rechargable Li-Ion battery. I don't use it more than 3 mins straight. It sas it works up to 40 C
I can see the beam even in daylight
I just got a 303 green laser in the mail. First 10 minutes I accidentally shine it into my eye.
I once got my cat to climb up a rock wall with a laser pointer once... It wasn't like a rock climbing rock wall, but one of those fancy fireplace rock walls......and I once pissed off an old teacher with it.
if you don't have a wicked laser you are not a true nerd, simple as that
Yeah, I really want one
Assembled my own from a 4 watt module, that count?
I ordered a nano from them!
Fuck wicked lasers and thier shithole customer service.
goochman 420 lmao the truth!!
Me I just lay in bed and shine It around and play with my cat nuff said ✌️✌
Need that in my life 😏
I use my green laser as a flashlight, just point it at the ceiling and the whole room is instantly bright green!
lol
And you could pull it out if you are ever getting robbed XD ("Stand back! I've got a laser pointer!!")
I annoy my neighbours
use mine to light my bud
+charles arceneaux powerful lasers are so hard to come by in australia, I wish I could smoke with lasers
I just got an ad for a powerful laser in the video lol, what a co-incidence.
I proudly own a 301 green laser pointer. I don't shine it at anyone, except cats (and maybe a few vehicles). But I mainly use it to laser-troll on houses in my neighborhood at night when it's dark.
I got one Since the age of 5 and do trick with them i carry 1 one with me everywehre 4 safety if someone is rude just point and them
I have a Wicked lasers arctic blue laser, I think it's a 1,000w or mw not exactly sure. It has several modes, low, high and strobe, constant, SOS and something else. Each one has a high and low power, I manly use mine for fun in foggy or snowy weather or shine it in the sky cause it looks like a never ending beam of light. I never have nor will shine it at anyone especially while operating a vehicle, once my friend pointed at my car when I was about mile headed the opposite way and I nearly crashed, no i didn't ask him to. And for a heads up to those which may have or be interested in an arctic laser from wicked lasers or one equal I was pulled over while driving because I shine my laser in the fog while no other cars were around for literally one second and I got let of with a warning that if I was caught it could be up to a $10,000 fine and 5 years in prison. Now that officers statement could have been somewhat false but idk. But if you ask me that's a bit extreme for just a laser pointer considering I was using it when no one was around that could be harmed other than me. I loved using it on the Miami and Hilton head beaches at night cause for some reason a lot of people used lasers for fun and so far mine was significantly brighter than everyone else I ran into and I found myself getting comments/questions from people that's saw the beam miles down the beach hour/hours later once I reached them. I blinded a crab in about a second unintentionally so then I put on the flashlight lens so it would shine a wide beam of light such as a flashlight only very blue and even then I had a kid 20ft behind me tell his dad that it was hurting his eyes, so I apologized and had mi fun for the night. I have ran a few test with my friends and had him point it in my general direction while I was around 10 miles away at night and when the beam passed near me it was very noticeable. Which for some who didn't know what it was well I could only imagine what would be going through their heads swing a bright blue beam that seemed to have no beginning nor end. Mine ran me around $300 US but to me it was well worth it considering they could be illegal some day down the road.
I use it at night when all the cats in my court come out. I make them all follow it and it gives me a sense of power.
LOL, the "thousands of reflecty things" in street signs and highway marking paint is 3M Glass Beads aka Scotchlite. I used to manufacture the product for 3M. It is cool to see some of it accidently spilled on the floor, the floor glowed under the overhead lights. Just a tidbit of trivia. And you are right, lasers can be fun when used responsibly! Our cat loved it!
lol my friend got a 1W laser with a focusing lens... so far we have lit a blunt and permanently left our names in my coffee table
I have a home made 2 watt laser just to burn things for fun. I wouldn't shine it at anyone, just some leaves or blocks of wood. Incredibly powerful though.
Original design military use, as you said, we used to pinpoint for air support when TIC came over the radio.
I once tried to take a picture of me using a laser pointer to write "HI MOM" in a dark room over long exposure time. It didn't work as well as I wanted. Other than that I just use it to play with my cats.
In the US at least, I believe you _can_ actually legally buy class 3B or even class 4 lasers in a handheld form, though they'd have to have a couple specified safety features (a key, and I think a switch, rather than just the pushbutton). Here in the UK, there's no restrictions other than you can't sell anything above 1mW (class 2) _as a pointer,_ though I'm sure there's many violations of that too. As a laser enthusiast I approve of the freedom for at least responsible consumers to buy, and experiment (i.e. play) with, these higher powered lasers, as long as they're sold as high powered lasers and not pointers, and basic laser safety tips (like owning appropriate goggles) are emphasised prominently by the merchant. Obviously people who abuse them (like shining them at planes, cars, or using them in any dangerous manner) should be prosecuted to the fullest extend of the law... but us responsible laser nerds aren't harming anyone and are actually helping to develop the technologies involved, so it'd suck to impede our pursuits. I'd also say there's confirmation bias here... responsible laser owners will rarely use a laser in public (outside legit uses like stargazing), so naturally all the uses you'll have likely _noticed_ were people being annoying wankers with them.
You're completely right, the only reason I have a laser and the only reason my friends want one at all is to mess with their cats... :)
A couple of guys at my school were using a laser pointer to mess with a squirrel. lol
play those hidden picture games with friends, so we arent all yelling "no left,- up, too far back right, its right there by the magnifying glass!"
I bought one at the dollar store yesterday so I can walk to the PetSmart and mess with the cats :3
I use our laser when I find someone shouting for help on top of our mountain ;)
I have a 125mw green $225. I like to shine it at street signs while I'm driving, even from well over a mile away it illuminates a modern street sign like it's daytime. Street signs have thousands of reflecty things which does wonders with lazers. I also burn stuff, pop balloons, play with kids & strangers in stores & at work, NEVER, NEVER, NEVER even *CLOSE* to anyone's face! I love foggy nights! Shining parallel with an operating sprinkler or water fountain is cool! The rest is secret.
I'd just like to clarify the difference between laser light and "regular" light. You said that laser light is columnated, which is not wrong, however that's not what makes laser light special. Ordinary light can be columnated as well, but what makes laser light travel so far is the fact that it's coherent. Coherent light is light that is one frequency and one phase. Meaning that all of peaks and troughs of the waves line up. Nothing overlaps and thus very little inter-wave interaction occurs.
I have a 5mW green laser pointer. I often shine in the direction of people to confuse them and then stop when they try to see were its coming from.
"Military grade", Sounds way more special than you think.
-a Marine
I have a 405nm (Violet) laser that I use for burning and other fun light stuff. It puts out 900mW which is insanely powerful for a wavelength that short. I never use it outside or publicly, it is VERY dangerous.
when im bored i go and scare birds flying by
I suddenly really want one of those.
OH REALLY??? How are they going to know that I'm using my 10 watt, High Power, Infrared, 940nm wavelength LASER when they cant bloody see it? Plus I can use different wavelengths. Nobody will see it coming as it burns out their eyes from their sockets and leaves zero evidence. And NO!. I'm not going to harm anyone. Just making a point to anyone who thinks they are very clever and know everything.
I taped my laser on a rifle and stood out on the balcony and scared the living shit out of people lmao
I have a red laser pointer where you have little caps that you can screw on so when you point it at the wall you see little shapes
As a pilot, I have been blinded at night by a laser pointer and it seriously BLINDS you, and when you are on final approach with another human life next to you, and now you cannot see anything only 100ft off the ground going 120mph, it is quite frustrating to know people are so nonchalant about these things...
I would never do that. I couldn't believe how soccer fans were using lasers to interfere with goalies with no concern of damaging their eyes. Pointing a laser at a plane is risking death of everyone aboard. I can't believe that guy only got 2 years for doing that.
I think having laser like alot of other things might be handy in emergencies. I mean besides the regular science type uses. But I do think purposely aiming at a plane should have much stiffer consequences to fit the possibility of the loss of life. Also I think they should spread the word of those consequences so even the idiots hear about it.
I live in town, so I haven't wanted to risk eye damage to others by taking my lasers outside at all.
Anyway I agree with you. It's no joking matter.
In the process of building a 6W Laser at 450nm wavelength. If all goes well in testing; I may build a Co2 laser in the 40-80W range for a laser cutting cnc machine.
I use it to look at beads of water to see what's in my water and also to play with the cat. :D
I use them for fun, great for summer nights pointing at stars, fireworks, across the lake, and yes I will goof around and annoy people. I have a purple and a green. The green is amazing bright and travels very far.
I build high powered lasers for fun. Anything from 100mW to 1.8W. These are used indoors with laser safety glasses. I mostly use them in my Electronics Classes to teach about the driver circuits for these lasers. I pop balloons, light matches, and burn wood. It's a lot of fun and impressive. However, laser safety is a must and laser safety glasses are required!!!
styropyro and sanwu 7w laser: Amatures
Seeker:What was that?
styropyro and 7w laser: Amatures!
certified laser goggles: yeah right
making waiters drop stuff is funny though, but you COULD get caught and get kicked out the restaurant though.
i had a pointer which can burn plastic at close range if it was black or the same color as my lazer, which was green.
Thanks for telling me where to buy them
I have a 2.1W 445nm. I shine it at a CD and it reflects the light as it melts and makes a crazy light show on any wall
I have this really powerful laser pointer, I can't remember how much it was advertised as but it is WAY more than that, you can go look it up on TH-cam, I have the SDLaser 303. Anyway, I use it at night and shine it on road signs while we're driving, just to see how far we can get it.... it's pretty fun and it's crazy how far it can go. :)
Putting laser pointers on wrist bands would change the way people fight with their hands. Blindness matters.
I m leaving in East London. ..and once royal hospital London using helicopter for heart attack case. .back to the way pilot get vision distribution with high laser light. .can't move forward and have to land in public park. ..and it's too late for patient. ..saidly he died...
I use my lasers for science experiments with fluorescent objects and chemical reactions. Lasers have many practical applications and can really support the advances in science, however, I am getting a bit tired of people misusing them. I think that lasers of over 1 watt (not 1 milliwatt) should be available to only people who are licensed to buy them. I think in fact that people should probably require a license to buy lasers the same way they need to get a drivers license. Further-next com
I have a little 5mw laser pointer and I have fun pointing at really far away places, I also like to occasionally burn some stuff up close and I have a effect lense that you twist and it's great for clubs
5mw cant burn
I have an Arctic blue laser, but I got the "laser saber" attachment for just messing around. That contains the beam and scatters it against a phosphor coating in a polycarbonate "blade". It can't spear into the sky and blind a pilot, and the thing looks like a movie lightsaber effect in pictures.
Well, as you probably recall, I've been aircrew on a night flight where the cockpit was hit with a high-powered laser from the ground. There's no doubt in my mind that it was deliberately and repeatedly aimed at us; there's no way any aircraft could accidently be in a beam path for longer than an instant. As a pilot, I'm not concerned that these devices are available to the public, but I am concerned that there's a lot of knuckleheads out there.
There's no law that can fix that, though.
For pilots -- information about reporting laser incidents: www.faa.gov/aircraft/safety/report/laserinfo/
Please make a video showing your "laser saber" i'd love to see that.
Yeah...we're not gonna do that. I tried that once. It's not the most photogenic thing in the world. I have no desire to be a meme.
th-cam.com/video/HPPj6viIBmU/w-d-xo.html
You can see my laser blade here: plus.google.com/u/0/photos?pid=5819011561199718850&oid=116492343752935835532
Hahaha yeah, but anyway thats a badass lookin pointer you have there and also, how much dd it cost?
It's a Wicked Lasers Arctic. Check their website, I don't know if the price has changed.
95mw laser at night in not to deep water makes for a interesting effect, makes you see fish swim around clearly at much larger distances than at daytime.
I owned a 50 mw laser at the age of 14 at around 2008... I owned a 200mw laser at the age of 16... I recognized how dangerous and disruptive the lasers where. I spent hours and hours of researching the potential dangers of the lasers. The 200mw laser I mostly used with a lens that broke down the beam to thousands of smaller beams on a nearly 100 degree range.... Lasers that are ultraviolet can cause cancer. If you own a laser pointer anywhere above 50 MW you should be wearing protective glasses most of the time as they can cause permanent blindness.
I use my laser to point at UFOs, not planes, if it is a UFO it will actually pulse back
I use my green 532mw laser for cutting black material, lighting matches, engraving metal, blinding robbers, and much more uses
Meanwhile we are sponsored by these overpowered green lasers so buy please. Don't use, just buy.
I use my laser pointer to point out problems in the machine to clients. Pretty useful when its cramped
My laser shoots 21 megawatts... enough to activate a flux-capacitor!
Lasers are restarted wth is the point? A strong laser can blind you in a mile second if it hits a reflective object
so is a 1w laser way to much i have one. is it e legal or is it bad to look at the light? when it hits the ground
I'm looking for a laser pointer for my beekeeping presentations. How strong does it need to be to be seen when pointed at a screen in a lighted room from 20 feet? Which is more visible; green, red, blue?
green
I think it`s ironic that there is a laser-pointer commercial next to this video.
I literally was shining mine up in the air out my window as I saw this video, they're just used to entertain yourself 90% of the time
I use my green laser pointer to increase my accuracy while hip firing. I have mine mounted on my full metal Krytac Trident CRB airsoft gun.
I have the Wicked Laser Arctic Spyder III. I have never had so much fun with a laser than with this one. I mean being able to mess with someone who is 1/2 to 3/4 of a mile away and up to 5 miles is just way to cool. Call me childish or even immature but its fun.
I had one and made my cat try catch it. Ahh those funny moments
I bought a laser pointer just to screw with my cat xD HE LOVES IT
you are so funny i like how you sad x amount of brightnes was overkill for a little kettin lol
where can you get stronger laser pointers or any at all, mainly green
I have a 2w (2000mw) 445nm (blue) laser I constructed myself. I use it to demonstrate light amplification by stimulated emission of radiation. Physics is a wonderful subject to study. If people want to use high powered devices they should have sufficient knowledge to do so safely. I don't think regulations would stop people from doing stupid things. You can't cure stupid so to speak.
I have a green laser pointer and I pop kids balloons and shine it in people's windows
