Powerful Lab Laser in Action

[Gunnishone]

What country are u in ??? Is that legal

[LegalSk8boarding]

@conciel8. GIVE UP PORN!!!!! NOOOOOOOOOOOO!!!!!!!!!!! Wait. Is there some in heaven?

[stickyfox]

A lot of people seem to think a laser is "lame" if it needs to be focused to a point to burn/pop/etc. Tip from a Real Science Guy: All lasers are divergent, meaning that over distance they spread out, reducing their energy density. You have to focus any laser to a point to benefit from its destructive power. Also, in real lab apparatus, we deliberately spread out the beam so that it won't damage mirrors and optics and so that a tiny speck of dust can't knock the whole beam out.

[HoorayforOranges]

@stickyfox Wait. Laser light utilizes a polarized parallel wavefront, which is a coherent waveform of energy. It isn't divergent in the slightest.

[stickyfox]

@HoorayforOranges Hi.. man, I forgot all about this video. I wonder why noone watches/comments. There is actually a teeny bit of divergence you can't get rid of. You can get very close, but no real laser has zero divergence. Diode lasers usually have huge divergence, like 60° or more; the optics are just carefully focused to make the beam as straight as possible. Some people want their lasers without a collimator since they are going to run it through optics anyway; it just adds more loss.

it is not so powerful sin u use magnifiers and it can ONLY pop up black balloons

[PhxSt0rmz]

IR filters?

[Pr3miuM]

Yes, IR light is filtered.

[laserfan17]

240mW green zero IR

[panhead1219]

@Pr3miuM You could put an eye out with those things.

[HighTechDealZ]

lame. you shouldn't have to use a magnifying glass to burn things, that is just bad design.

[bobfather123]

nice do they plug into mains? or what?

[thesouthernlad]

are you trying to sell these or what???

[BishiSwordsMan11]

song name please?

[Pr3miuM]

Jesselyn - Contact.

[fenderboy19]

u guys need to get a life!!!!

[GingleGangle1]

I got 2))

[SGTNAPALM333]

that thing could blind so fast. i dont even want to touch that thing.

[happygameshow]

I agree could do some damage in the wrong hands.

[qwertzsa]

cool dude,

name of the song?

[hksmrchan]

power? THIS... IS SPARTA!!!!!!!!!!!!!!!!!!

[freddie7456]

how much power is sparta?

[spagmodius]

It's over 9000.

[Dragonrider202]

correction 9,1 gw

[cheli89]

i just got a 240mw laser on ebay i don't know if it will burn stuff

[pleadster]

it definetely will

[waitemattwait]

noice X)

[atariretro]

the tunnel scanner is amazing, i can see some integration into holograms in the future. Whats the music track?

[Xenodius]

I know a guy who has a 421mW Hercules handheld... now THAT thing is a beast!

[TITANTOWER]

that was really cool, but everytime I see these laser videos, I keep cringing, like someone might catch something on fire in their home, God forbid.

Anyway, even as a lser novice, I may get one; it makes me feel like a cross between a kid and yoda.

[TX3090]

how come the beam isn't easily visible like other videos?

[Raidenx89]

put your eye up to it for 1 cm away and tell me what happems

[testaki]

nice video, but come on m8s burn something else, be creative.

[deadsnowmen]

a normal sunbeam can light a match

[johnpower0]

can i borrow that? my lighter ran outta fluid and i need to blaze some chronic? would that work?

[Helioplasma]

To bad every laser has a beam divergence... otherwise you could burn a match at 50 miles!

[nitrolightning]

I have just ordered a different brand 240mw green laser, i hope its as good!!!

[imagay112233]

how u do tht scaner thing?

[cwest2005]

put you're eye in it

[Silento]

haha thats such a stupid response

[mcel85]

What kind of laser is the laser you show in the part "no high power laser pen..." It is a wicked laser, right? how much mW is it? Looks like and CNI.

[mcel85]

Ow ik zie nu pas dat ik het eigenlijk ook in het nederlands had kunnen vragen :P

[cyrillium1960]

your video laser 532 nm is the best,exellent !!!

[mcel85]

it's 240 mW, why do you still use a external lens to burn matches or paper?

[ixfd64]

It's probably due to the actual irradiance. Output power is only one of the factors that determine burning capabilities. The power will have to be focused well enough to burn. Obviously, a 1kw laser won't do much if it's spread over 1 sq. km!

[Pr3miuM]

Correct ixfd64! The initial beam diameter is for some things too big for burning. However whitout external lense I can still burn a lot and the hole is also bigger. It's all about irradiance like explained.

[BernieDK]

Damm i hope i can afford it someday (plz dont laught at my 75mW lol)
