900mW IR Laser burns a white wall

[233AK]

5 days later....oh look a mark.

[creeksidenumber1]

nooooooooo the wall is burning

[Jamien321]

haha this is so fake

[Melamamoduro]

@Jamien321 isnt fake... you can light a pillow whit a laser

[javy0005]

so i know your not supposed to look at high power lasers without goggles but even if you cant see this ir laser does the beam somehow reflect like i know if i shine it directly in my eye it'll kill it ...the reason im asking is cuz i wana fuck with people u know randomly set shit on fire but im afraid ill hit a reflective surface and blind someone

[TheUSAHaxor]

lazers are made so you can go to parties and pop balloons and watch the people scream

[BlairHooverDrums]

and then your house burns down

[ExtremeBogom]

Hai guys can some1 help plz??

I shone this directly into my dick hole, and my dick caught fire.

Anyway I can reverse the scar tissue??

[KanyeTroll]

@ExtremeBogom I know how that feels, because I have gonorrhea and IT BURNS!!! In your case I'd recommend buying a new dick, and possibly a new laser.

[TheSuperhack3r]

I hope your wearing glasses cos if you could see it then it would show how bright it would be. Even looking at this dot WILL destroy your eyes!

[UncheckedIrony]

Then your mom walks in.

[xs239]

Try that on your balls.

[xs239]

Trythat on ur balls.

[Theandy1000]

well..you may have to paint your wall all over again ;)

[DemonLDR]

I use it to melt peoples faces.

[limrome]

You should burn all the way through =]

[magetrix9]

@dynametal lol i love this conversation

[gamerzIV]

I don't understand something.Who cares what colour the wall is....

[ppRoss]

@gamerzIV radiation excites materials which absorb light.....like black things. so a white wall burning suggests a reallly powerful laser. i would guess

[shittyfuck]

i will simply use a black pen,instead of using 900mW laser,that's more faster and easier to make your friends' house dirty.

[dynametal]

@magetrix9 wat the fuks ur problem. u fort it was real n now ur upset becoz ur recently realised how much of a dumb bastard u r. fkn angry twat

[magetrix9]

@dynametal lol i love it when people assume crap oh yea i'm really pissed off about how dumb someone is... that's sarcasm if u don't know that also learn to type

[dynametal]

@magetrix9 yeah its funny how u wer screwing at me about sayn its fake and now you're all of a sudden sarcastic and anti-angry. mood swings???? i know how to type dip shit, if you can't read short-hand typing thats ur problem, not mine!

[magetrix9]

@dynametal lol arguing over youtube i dont care

[LilyVid1]

wht is the light so weak on the laser

[blacklightstudio2]

@LilyVid1 IR light is not visible to the human eye

but I don't know about that weak red dot we see, maybe it's an exstra pointer to show where the IR beam is

[blacklightstudio2]

@LilyVid1 no the VISIBLE light is weak on the Laser, the actual light would practically blow your eyes out

[JuggernautRecords]

more like 9mw lmfao

[blacklightstudio2]

@JuggernautRecords the red dot you SEE in the wall looks like something weak, but IR light is not visible to the human eye.

the IR light of this laser would practically blow your eyes out

[ohhhwell]

@nascarm2008 Shine it in your eye, shit bricks when everything goes dark.

[dynametal]

FAKE!!!! video editing software was used!

[Godzilla2456]

@dynametal its not fake douche bag.

[SamsoniteNM]

i doesnt burn the wall lol.. its buring the painting or the paper

[mewrox99]

I sure hope you had IR googles.

[nejixdragon]

ima buy that and use it on people :D

[TimpBizkit]

Imagine looking into one of those things you'd be like "Actually it's not THAT bright.. AARGGHH MY EYES!! IT BUURNNNSSS!!!!!" Although the retina has no pain sensors

[emiliongo007]

this laser looks like weakly laseer but it isnt

[Worrun]

Point it in a cats eye!

[ShittyRecords]

@Worrun

Basterd. Even if I do not like pets.

[TiagoTiagoT]

curious, usually IR doesn't look red on most color cameras....

[Uberownager]

That because it's hard to make a diode that puts out only one specific wavelength. The frequency interval it puts out is a bit wider, and will include some of these visible red waves. Which is the same reason IR lamps for IR cameras glow in an eery "dark"-red manner (the more expensive the model, the less visible light you will see)

[TiagoTiagoT]

But often, IR looks like some other color, like green or purple, often much brighter than expected, either the laser in this video is actually a near-IR and not really IR, or the camera is quite special

(continuing on a second comment to fit)

[TiagoTiagoT]

(continuation)

The filters that separate the color components for each pixel usually also filter out light in the infrared range, but just to some extent (as you can easily verify by pointing a TV remote at your camera while holding a button down), and often the green and blue filters for some reason tend to let in a tad more IR than the red filter,

(grr, who came up witht he great idea of having such a low limit on char count? third comment should be the end)

[TiagoTiagoT]

(Third and gopefully last part)

and not always with the same intensity, some might even allow different bands of IR pass more or less easily than the filters for the other color component. My cell sees IR as purple, my webcam sees it as greyish green, though it does goes more to the red side if the IR light is weak enough.

[iburnudown]

@lovelylamp its an ir laser not a regular lazor if you were looking at that laser threw night vision or something similer you could see it a lot better

[lovelylamp]

i thinks its low and batterys

[ThePlaneboys]

@lovelylamp its not its infra red you cant se IR unless you look at it through xenon

[mapleguy1029384756]

@lovelylamp Your retarded thats what 808nm looks like

[IForgotMyDeodorant]

OMG it's a freaking infrared laser ofcourse you cannot see it because YOU ARE NOT A CHICKEN! it's still ultra powerfull and you could do wonders with it since it isnt reflected in white stuff. I wonder... How much does it cost?

[survivorevil]

mmm of course is reflected... just because you cant see it doesnt mean its not reflected, whats why you gotta use goggles

[machomamajr]

lol the laser sucks balls

[iamthewalrus97]

so to test his new laser he figures i know ill burn holes in my wall :)

[wazzup784]

And that's how house fires are started.

[stigg46]

@wazzup784 lol no its not !

[Belmaktor]

THe reason you can't see a beam and that is isnt that bright is because IR cannot be seen by the human eye. That red dot you saw was just extra red visible light emited from the laser.

[becksq9]

battery low ???

[laserfan17]

no it looks low because this camera has an infrared filter and most of the infrared light are blocked without an infrared filter you can se the beam and it looks like a really 950mw infrared laser

[RAZlaad]

expensive them lasers

[emul96]

that is sumthing 100-150 mW laser

[HifeMan]

it not that powerful xD

[iminyourbasement]

@HifeMan i will shine one in your face and the you can tell me if it isnot powerfull

[snelpiller]

why would u want a laser that u cant see with ur naked eye? :(

[pseudonomen137]

There was a time when CD players were all the rage. Did you ask each and every people who owns a CD player why they would want a 780nm laser? Nah.

Believe it or not, visible lasershows are just a minute fraction of the applications of lasers.

[Hoarderify]

@pseudonomen137 .... so most ppl think lasers are only thinks that makes the ultra mega super light show at concerts ? lol L.A.S.E.R (Light Amplification by Stimulated Emission of Radiation) is .... bigger than normally youtube user think so google it or search on wikipedia befor u post this shit :D

(i just wanna tell this way u re totally right ;))

[gtq838]

well for one thing to make it less visible to the human eye... more culvert

also, I think ir lasers burn better because they are a lower frequency... also many objects that reflect coherent light can absorb IR light... glass is a perfect example... when they laser cut glass they will use IR because glass absorbs IR light and visible light passes clean through it making it very difficult to cut

[survivorevil]

maybe you meant higher frequency, a lower freq would be uv, violet or blue

[Rib640]

Correction:

High frequency - UV; Low frequency - IR

High amplitude - UV; low amplitude - IR

High wavelength - IR; Low wavelength - UV

[sp00nf33d]

wrong,

Frequency:UV > IR

Ampitude Seen as brightness: either

Wavelength: IR>UV

[Rib640]

@sp00nf33d Isn't that what I said? (aside from the amplitude)

[sp00nf33d]

yehp :P i was only meant to correct amplitude but i got carried away

[Rib640]

@sp00nf33d Ah ok then! ^^

[gtq838]

IR Light

1 x 1012 - 4.3 x 1014 Hz

UV Light

7.5×1014 to 3×1017 Hz

Hench UV light has a HIGHER frequency than IR light.

You sir are confusing wave length and freguency and they are two seperate things. I know it maybe confusing too you but you can rest assured that I'm correct in this case.

[survivorevil]

thanks for the explanation

[magget16]

red lasers cant get up to 900mw

[pseudonomen137]

Cars can't get up to 20mph.

Burgers never make you gain weight.

And this is why you should believe everything you read on YouTube - the equal-opportunity forum where everyone gets to pretend to be an expert on everything!

[Shamizle123]

lol

[sacredgeometry]

:) thank you for that, it made my day

[timorbit]

I've noticed an increase in that as well... suddenly everyone is an expert in everything.

[regnighc]

@pseudonomen137 Hes completely right though this is BS

[AnselmoFanZero]

@pseudonomen137

XD

[LeonMC84]

@pseudonomen137 like that!

[legocallofduy]

@magget16 its not really red its IR and the camera picks it up as red

[blacklightstudio2]

@legocallofduy Cameras normally show IR as white I think, the laser probably have an extra red dot to show where the IR dot is

[pseudonomen137]

@legocallofduy and blacklightstudio2

No camera tricks or other lasers. Its 808nm, which typically is invisible to the human eye because our eye's sensitivity to 808nm is VERY VERY low - BUT its not 0!

Most people can see 808nm light, but just barely. By packing so many hundreds of mW into a small area you can see it as a nice faint red spot.

[magget16]

@magget16 I know a fair bit about lasers asshole, and handheld red lasers definitely can't get up to 900mw. I dont even think green can, though they may be able to. There are lasers that go way above 900mw , but they need to be bigger because of the power.

[bulltex95]

@magget16 its not a red laser you fucking idiot

[magget16]

@bulltex95 and it's not 900mW

[Sapoboiazu]

@magget16 any laser can get to any power - it's a receiver,which turns electrical energy to another energy,so you can theorically get it to infinite energy just applying more electricity,the only problem would be the internal resistance.if you just believe in the existence of 5 cm laser pointers maybe you should go to dragonlasers website and see what is really a laser.

[BurninglasersFun]

@magget16 are u fukin noob read the text 900mw IR laser IR=infra red u cant see it fag and perv

[TommyDeBest]

wow i thought the camera would pick up the IR brighter

[Dkooler1]

thats not 900

[tullgutten]

mW Not MW

[Jarren95]

milliwatt not megawatt :D

[eldestsucubus]

i wonder what that would look like under some night vision goggles

nice laser btw, fuck all the dickheads saying its fake. too bad i could never import something like that into australia any more because a bunch of dickheads shone them at planes.

[AlessandroAUS]

You can import laser modules and complete the laser yourself. As long the device is still in component form, ie not fully assembled then it is legal.

[GodlessViking]

There goes your security deposit!

[pseudonomen137]

Haha, totally! I had to pay to replace the carpet in my last apartment because I dropped a soldering iron and it burned a nice hole in the middle of the living room floor.

[graveheat3]

divez2, you just got owned dude. Awesome

[divez2]

hey guys. this video is fake. how cant you see that?

[pseudonomen137]

Hey man, I know the rage nowadays is to run around youtube calling every video a fake, but if you can't even give a single reason why, you're just making yourself look stupid. So while I could take the time to insult you, you've already done my job on your own.

If your comment was actually serious, perhaps you have some reasoning to your comment?

[divez2]

okay, i'll give you a reason. a 950mw laser is A LOT brighter. that looks like a normal cheap pocket laser.

[pseudonomen137]

Yes, but if you'd bother to learn elementary physics before critizing me, you'd know that 808nm near-IR is nearly invisible. I actually addressed this in a comment earlier.

In fact, a 100W 808nm spot would appear less bright than a few mW of 532nm, and 2kW of 10600nm CO2 laser (such as the industrial lasers used to cut aluminum) is completely invisible!

[divez2]

oookay... thanks for this lesson... where did you get that good laser and how did you learn all this? you seem quite smart.

[Tawaxyon]

By just commenting back just proves that you are a little kid living inside a cookie house.

[MasterHacker01]

how do u know i live in a cookie house?...STALKER!!

[Tawaxyon]

No.. I'm just your neighbour ^^

[BRMack02]

is that wall flammable

[mattisace2]

thats not 950mW

[pseudonomen137]

You're right, it was more like 945mW or so, and I'm sure it wasn't exactly 945mW either =O

[mattisace2]

cool laser though where did u buy it

[buddy39914]

that looks like 500mw (hulk)

[fishyfish777]

Don't burn your new-looking wall

[Kyteq]

if it's IR wouldn't the camera pick it up really bright?

[FIoatZel]

dude this is near infrared..i think some cameras cant pic that wavelength up

[pseudonomen137]

Yep, its near-IR - your eyes will just barely see it. You wouldn't see light from a regular lightbulb if it were emitting 808nm. We can only see it at all here because we have a very slight sensitivity to 808nm, and that there is a lot of power in a small are.

Most camera's will either filter it out, or incorrectly portray it as a huge white/bluish/purplish blob. However this was recorded with a Canon Xh-A1 3CCD camera that is able to represent it pretty true-to-life.

[Mike0344]

holy mother of buddhas dead half cousin who died in a civil war thats powerful............dont ask about th bit b4.........

[dlinkdj]

how can i make the lazer more powerfull any ideas? does it have to do with the diode cause im gonna buy a dvd burner x16 tomorrow

[BurSchnart]

Say what you want, i wont believe it. I dont care about what he says etc.

[pseudonomen137]

I actually havent had the time to check these until now - no I haven't been rating yours poorly, but I would have. The "I don't care if its true or not, I'm just gunna say its fake anyway" is a classic tenant of the 'idiot' philosophy. Why make trouble?

If you'd bothered to post some evidence that its fake, I'd refute it now but since you're just going on... well... nothing apparently, I think my job is done.

And please keep your response civil or I will remove it. Thank you.

[NickTuber]

yes, because all this guys videos are definately NOT lasers, all do NOT light matches and pop balloons, all are DEFINATELY under .05 mW, and he does NOT have some cool lasers most people will never touch.

And my message here is "NOT" dripping with sarcasm.

[BurSchnart]

l0ol the video owner is now starting to vote bad for our comments because we are right.

[NickTuber]

actually that was me and other who are right.

Lol...

Check his other videos.

[jayls5]

No. You're wrong, and people should vote your comments bad because they are. They're speculative statements that stem from a lack of knowledge of basic science. Look up the range of the visible spectrum in nm (nanometers). Then look where infrared lies. Guess what, you can't see it. That's why you barely pick any of it up, yet it has the potential to burn. Industrial lasers do this. Tool.

[PhantomKode]

Theres no way thats 900mW, a laser of that kind of power would be so bright man

[iforgotwhatiwasdoin]

It's infrared.

[PhantomKode]

oh, cool nickname btw

[iforgotwhatiwasdoin]

That is the first time anyone has ever said that! Thanks! Your's is cool too.

[pseudonomen137]

You could have a 1000Watt laser that's completely invisible to the eye - in fact they're used in industry all the time. CO2 lasers at 10,600nm are invisible. At the 808nm in my video light is normally considered invisible, but at these intensities you can faintly see it. It would help you to learn some basic physics to understand this.

[RobTFirefly]

Cool way to burn a hole in your security deposit.

[Termi87ITA]

Can 808 nm lasers burn white paper and trasparent plastic (like plexyglass)?

[GUNSIMON0077]

my 240 red burns better than that if its IR how come u can see it. If 900 mWs were going through that pin prick it would burn through the wall

[thebucketmouse]

your 240 red doesnt burn white colored things as good as this laser does. and it's barely on the edge of the red-infrared line, so you can kinda still see the red

[lXlNismo11lXl]

I Have A Blu-Ray That Can Do That Also, But It's Only >110mW.

[rocketparrotlet]

Since blu-ray has shorter waves than IR, it is absorbed much more easily by lighter colors. Either way, pretty cool!

[Communicatee]

cleaver.

[Bcf720]

wow smart..

[Atmosphirboy]

haha, nice way to burn your house down xD

[ZEATER666]

PRETTY WEAK and i dont think its 900mW thats weak for mW and it would much bigger

[pseudonomen137]

Got anything to back that claim up, or is your mere proclamation under a YouTube video all the credentials you need?

[LRMNmeyer]

Notice the title "900 mW *important* IR important* laser burns a white wall", IR is invisable, and very little of it is seen by us. If this was a cheaper camera that sees IR as a bright white light, you wouldn't be able to tell what's going on.

[/spoonfeeding]

[Nugburner420]

i agree

[youser323]

THE FUTURE IS HERE !!!! Xp

[urvidsuks]

mine is the same colour and it looks exactly like that on a white surface and is only 1mw but doesnt burn or heat up atall why is that?!?

[bali105]

Because 1mw is 1/1000th of a watt....this laser is close to 1 watt...big difference in power output.

[Xxero0]

NICE

[steelcrate]

Snipers used to need laser to aim... Now they won't even need ammo ^^

[1958j]

green is more visible and brighter than red. and its and ir laser so it doesn't have a colored beam

[mercanaries3]

1-5watts i think

[maxkillz2]

nice laser, I have a green one that can burn a white wall too but it takes a bit longer. I think it was a CNI pen style laser. would you happen to know what kind of power I would need for a green one to burn a white wall?

[cjdelphi]

That's one powerful laser, it would be impressive if it was in the visible spectrum which makes it all the more dangerous, i can imagine customs?..

Oh it's only a little red dot, let's take a look inside, ARGHHHHHHHHHHHHHHHHHHHHHHHHHHH­HHHHHHHHHHHHHHHHHH MY EYES!!!!

owned.

[DarkStare100]

Lol yea, Get past austraion laser customs lol.

[rcmustang44]

thats not 900 mw

[pseudonomen137]

Yeah, I lied. Its actually closer to 940mW. Sorry, you caught me

[SkylineR034]

940mW.. are u crazy its more like a 2mW at the MAX!

[Ham549]

2mW would not burn anything

[danagol1985]

No, it appears to be a very weak laser, because the human eyecan not detect IR very well - if atall. However this does not mean its not strong. Look into it, and im sure you can etch pretty pictures on your retina!

[Ac3ssD3N13d]

hahah! I hope this dude accidentally burns his house down.

[babybobby69]

this aint a 900mW, if it is it must be fucked. i have a 200mW that would burn your house down in the time you made them tiny holes. lmfao

much love x

[pseudonomen137]

There's a big difference between burning something that's black (absorbs light energy) and something that's white (reflects light energy). The point is imagine what this could do to black objects if it can pull this off with white. It'd sure make your 200mW (which would not burn down your house BTW) look like crap.

Seriously guys, what is it with YouTube commentors and their insistence on showing off their ignorance with arrogance. No guys, you aren't genius experts at EVERYTHING...

[jonathan362]

why would you get one tho? whats the point in burning a hole in a wall....

[888888888306]

yea, green ones are much brighter then the red ones, but id like to have a red one, i meen, come on, thre so powerfull

[DarkStare100]

This aint red its inferred!

[vHORSEPOWERv]

yea i agree its gotta be a strong laser.. but do red lasers not make as much light as green ones? i mean even the 5 mw green ones emit waaaay more light than this. someone reply

[DarkStare100]

Dude its Infer red its nerly invisable

[pseudonomen137]

Do not confuse light with perception. mW is a measure of power. A 10mW green laser puts out exactly as much energy/power as a 10mW red/ infrared/whatever laser. However, our eyes PERCEIVE different wavelengths/colors at different efficiencies. We perceive ~green the strongest, and it tapers off towards red and violet. So 5mW of green will APPEAR less visible than 5mW of red, but theyre both equally powerful. You can even have plenty of light/power at microwave wavelengths and not see it at all.

[PlayerHater117]

Ill be sure to save you when your house burns down.

[772144]

very nice video

[mafiaboy797]

808nm isn't really true IR its more known as NIR near infrared

I thought
