- This video compares lasers of powers ranging from 200mW all the way up to 2W. This is part two of my video titled "Green Lasers: What Can Certain mW Do?".
This video compares lasers that are focused to a point. High powered lasers vary widely in beam diameter so to keep things simple, all lasers here were focused to the smallest possible dot.
ALWAYS wear laser goggles when working with lasers over 5mW to prevent permanent blindness!!!
Check out laserpointerfor... to learn more about laser pointers, lasers, and laser pointer companies! I have been a member there for 8 years, and have received a bunch of help from the knowledgeable members there!
People watching video of focused light igniting objects...
"can this burn you?"
i was thinking of that lol
can you invent a laser that will blast stupid out of the comments ?
I can't see your comment.
lol
"Have you got a light?"
"Why yes!" *pulls out laser*
@HALO3SHIZAL you could easily completely destroy an eyeball with 50mW too.
Your mail man must be shocked by all the high power laser packages you order...haha, nice video!
Look up "Sam's Laser FAQ"...it's a great resource for info on lasers.
Wow, a StyroPyro comment with one like, this is rare to come across nowadays!
I'm so excited i just ordered a burning laser
Great explanation of the various power levels of lasers. Well done (hopefully safely!)
nies
Thank you for both this and the previous video. I bought a laser (one of those fake "
@zxcvbnmjfjf I ignite paper with a $1500 precision laboratory laser cuz I'm that fucking awesome.
awesome very useful I'm getting a 500mw
good for you
Are your eyes okay?
@@RetroPlus im actually legally blind in one eye now
@@jessegarlick2583 I'd say this is a joke but I have no clue if a 500mw can't blind you lol
@@napoleon5174 didnt the video give you some kind of hint?
@ocool100 I very rarely use adjustable drivers so I never really use test loads. In the rare case that I ever did use a test load I just used a few rectifier diodes in series, costs like five cents.
imagine this guys electric bill
oh gawd
gee i wonder how much more power a 2W laser uses than a 60W light bulb.
@ocool100 You don't need a test load if you intend to max the driver. It only goes to 440mA which is perfectly safe with a LPC-815 diode. Some people run those things up to half an amp.
I think that you should take a bunch of LAZORZ and put them together in such a composition to make a DeathStar.
Such lasers already exist... They use them to cut metal for car parts.
Im curious i always thought lasers producing the wavelength of redlight were more effective burners
my 200mw laser doesn't even burn matches
whats wrong wiv it?
Daniel O'Neill you got screwed
Dont worry, nothing is wrong with your laser, he presented the wattages incorrectly... The one he shows as 200mw is more like 2w.
k
Richard Gibson no he didn't.
Wickedlasers or Laserglow do t c om
how do you have so many laser's
"Your father wanted you to have this when you were old enough but your uncle wouldn't allow it. Your father's lightsaber. This is the weapon of a Jedi Knight."
2000MW=2W
Which is the first green laser he uses? I want a 200mw laser
What do you have those lasers pointed at while inside? Metal would reflect right? Is the beam less powerful when reflected?
light is less powerful when reflected (depends on mirror), he probably has bricks in the back. Since house mirrors absorb 10-15% of light I think metal absorbs more light and reflects only 40-50%
And I'm sitting here with my £3.82 5Mw thing thinking the little specs of dust make my beam look amazing! :D
hi, nice videos, what do you think of the wicked lasers s3 1watt krypton laser? and where did you get the 2 watt laser?
also, an idea for a video or two-- what the beams look like in the sky at night, and there approx range in miles/km
and what street lamps (with light sensor) you can turn off with what laser , at what range?
keep up the great work =]
it's fun how 2W lasers are now handheld
At what distance can a 2w laser go and still be visible?
it stings like a mother, and leaves a nasty deep burn, especially with a blue/violet laser.
Imagine making the perfect Gundam diaorama with these.
Where do you buy all these high power lazers? I would very much enjoy to have one.
who else is watching his old videos
at 100.000W the international space station can melt any point in the world
how did you made those cool lasers
Ebay now has restrictions on laser pointers over 5mw however you can still purchase laser diodes from ebay ranging from 5mw to 40w BUT you must know how to assemble them correctly using drivers and heat sinks.on line try WICKED LASERS
they sell authentic powerful hi quality lasers BUT they are expensive..Dont be fooled by chinese lasers, a true laser 500mw Plus MUST have a sticker on it that says (DANGER class IV laser) NOT class 3b or 4b. All genuine lasers over 500mw are class IV lasers
See my homepage for experiments using laser. Click the flags to translate.There are several easy to do examples to split the beam, modulate on of the two and then recombine them to produce low frequency beats. These beats should be able to induce currents into the body to transmit sound or steer muscles if used with high power lasers.You dont even need a laser, this can be done with ordinary light and heat radiation as well.The double slit experiment mostly is done with an ordinary light source.
what is the model of the first laser in the left( the brightest blue)?
I want to get a laser to kill ants. Will a 200mW laser set my house on fire or damage walls or something?
So what do you put on the other side of the wall? I can imagine your neighbor walking into their house and see a laser going through their kitchen.
does it matter how close you are to the laser?
Nice im getting a 3.5W laser
@MinaCraftar but it would be an endless saber. it will go on untill it hits somthing and destruction (the celing, moon, planets, distant stars)
so basically 200mw-2w will light a match. I wanted to see what a 2w could do that a 1w couldn't do or what a 500mw could do that a 200mw couldn't do. you see what I'm saying. great video anyways.
A 200 miliwatt laser is only a 10th of a Watt, a 2 watt laser would be 2.000 milliwatts!
No need to shout, you nearly deafened me! :
LOL
I recently bought a 5mw blue lazer off ebay but it looks very powerful also how much damage do you think i can do with it
+Konstantin Demenko There are definitely 5mw blue lasers, however they are single mode diodes like green lasers instead of multimode like high powered blue lasers.
@thecomputerman12121
what about a 1 Terra Watt X D
if u were to do that u could burn through a planet X D
Hello, everybody ! Is anybody can answer on my question? If I will realise good cooling (computer cooler ) for 200mW laser, is it possible that it will work for couple continuous hours?
Thank you
I have a 50 w laser cutter that just about cuts through 3mm acrylic at full power and slow speed.
aq bende bır tane 100 mW green laser var arkdaslarım sen kafayı yemıssın olum dıolar bu adam ne o zaman ?
I have tried many different wattages of lasers up to 2w... And this video is inaccurate... Either you are over exaggerating their power, or are displaying incorrect power outputs... Because the one you said is 200 mw acts more like 2w... And i have a 2w laser in handheld, and your version of a 2w laser, seems more like a very high powered laser with a cooling system... Similar ones ive seen like that are more like 20 watts...
I think you mAde an error in power outputs... Someone on here must agree with me... It seems like you decreased the wattages of your lasers by a factor of 10...
someone shout develop a 5000W laser that emits in a 'burst' and make it do a 'pew pew' sound :D
I wonder how his neighbors deal with all the light, either he has no neighbors or he has no windows
Because of this people laser rental companys get realy great problems because of lasersafety... "There is a laser, help it will burn something"... poor, very poor...
A kid can go to a local electronics store and by a 24x dvd burner. Then build a simple LM317 driver circuit. Then it's as simple as asking his parents to buy an aixiz laser module.
Just tap the old diode out, put the new one in. Solder up the driver to the diode. put in a altoids tin and turn it on.
All the kid would have had to spend is around $40 which is easy for kids to get these days.

hey man nice video i wonder if you or anyone reading this can help me i need to set up a laser maze as part of my precentation it will b in slightly lit area but i don't know if to buy alot of lasers or just this one and bounce it with mirrors since you have one would you try bouncing it and see if the dot gets too big?
by the way i will be the only one going thru the laser maze of cource with safety glasses as part of a mition impossible kind of thing
Information in this video is not relevant; the author is mixing apples and oranges.
Proper comparison would include few powers, one wavelength and one class (cheap or quality).
Red will alway deliver less energy than a green one at the same power. The smaller the wavelength, the more energy it delivers.
Also, cheap lasers deliver less energy than expensive ones, per mW of marked power.
Comparing desktop lab grade lasers with shoddy pointers is not something that can be considered relevant.
Sunlight is about a 1,000 watts per sq meter, but is of all different wavelengths. Lasers concentrate them at a single wavelength or color. Multiple wl would interfere with each other and all be focused at different focal points according to the optics it comes out of, like magnifier and the (imperfect) hot spot, thus why we can't have effective "sunlight lasers". I don't know theoretical limit to how many photons you can pack into a sq mm but it's definitely enough to cut through metal, etc.
Unfortunately eventually the "tip/end" of the laser beam would fade out because our mirrors are not 100% perfect... Even the best mirror that humans can make absorbs quite a bit of light and thus even a laser would eventually be completely depleted of energy.
Infact, the energy would be depleted so fast that if you were to turn off the laser the laser beam would turn off instantly for your eye (because light travels so fast).
They're not illegal in the USA at all, so long as they follow FDA guidelines and have safety shutoffs and labels. You can buy any strength laser (yes, even Class IV) premade or piece by piece, and legally have it mailed to you from anywhere in the world, as long as it has safety shutoffs (i.e. require a key to operate, or safety switch and "pull-pin" like the WickedLasers products do).
0:22 "pyrotechnics can be ignited with a 200 mw laser"
And you held it with your bare hand?
Apparently hands are quite good at negating laser damage... because of transparency
Something you might not have considered is your hands don’t combust like pyrotechnics.
It's just flash paper.
@@overloader7900 At certain wavelengths maybe, but you'll still get a nasty burn from most high power lasers.
You actually can buy green lasers of any power fully assembled, as long it complies with FDA safety requirements (at least in the US). Also, it is not sensible to build a green laser because it is very complex and a lot of things can go wrong, even if you do manage to make one, the beam specs will be very crappy and not worth the money spent. One more thing... stay away from wicked lasers.... the quality of their lasers are very exaggerated and not worth the money they charge you.
@Astromchaser
Red lasers are the darkest in the wavelength spectrum since it is closer to Infrared
Green is the brightest color to a human eye...so a 5mW green laser will have a visible beam at night.
Violet-blue is closer to UV radiation..and closer to a black light color so the laser beam will be much hotter and not as bright as green at 5mW
you need 250mW of red laser power for the beam to be fully visible
@Joni13795 Basically, red is weakest, then green, and then blue. However, that can be switched around by what mw they are. e.g. 100mw red vs 5mw blue. 100mw red is better. So if you are someone who likes lasers, but doesn't want to burn your house down, get a 5mw green or blue. With 5mw red you can't even see the beam, so I wouldn't recommend it, unless you are using it for presentation purposes.
being honest here... I need a small laser piece with solid beam, of violet color. I mean small and solid because I want to toy around building a lightsaber HILT internals for a cosplay. I just need to be able to see a beam of energy inside the hilt when I open it. Where can I find such laser?
@styropyro hi styro just a quick question i recently bought a 200mW laser green from a website that if never ordered from before aka:Mixwall.co.uk now this is also my first laser so i dont know much about lasers so my question is what are the chances of it being good and good meaning :burning matches popping balloons cutting tape etc thanks :)
Please help !!!
My 10 mw violet makes a match very hot but doesnt burn.
What to do?!
i will buy one of these lasers if im allowed to
If beam specifications are equal, frequency affects burning the most. Smaller the wavelength the better at burning things, like your eyes. OD4 safety goggles that are shipped with most of these dangerous toys are insufficient to protect your eyes from direct reflection from 1-2W+ power levels. You need OD5.
I just bought a 200mw green laser pointer and it is no way near as bright as yours on this video!! It doesn't seem to light matches but can burn black objects, slowly. Have you modded any of these lasers or have i just been duped?? My 200mw doesn't seem any different to my 50mw :( and the beam is weak in comparison to yours....please help!!
questions for noob like me
1. these are shown at close range like less than a meter from the source.. how far, lets say for a 300mw to still be able to ignite the steel wool.
2. what does the wavelength tell us about?
3. is color anything relating to wavelength or its just selectable at any wavelength?
thx!
How many mw do you need to start wearing googles
Five mW and up is the point in which you have to wear safety goggles.
A 2W argon lasers can be seen on the moon (search Surveyor vii moon and laser ). Can these 2W lasers make it to the moon ? Nasa photo: history.nasa.gov/SP-168/p80a.jpg

I managed to light cardboard with my 1W 445nm. I was intending to write on it and suddenly it started glowing, so i turned it off and removed my goggles and the black mark shot up it and a flame licked out. I put it out quickly because I was in my living room.
Those are sweet lasers, 2w + wow pretty dangerous and can i assume the last few or so are custom built? Or can they be bought on open market? I know wicked lasers brand are kick ass and super easy to increase power output too. Do you have any from wicked? Whats yuor fav? Thxs
I want to combine a precision tracker with a 1W laser to make the world's most effective bug zapper. Not sure how I'd make it absolutely safe. The tracker would only track tiny moving objects like insects, not macrofauna like humans, but stray reflections could be a danger.
I think he got the right glasses before he began to do all this.
Btw > 5 mW lasers aren't allowed for people without license or specification (or w/e you call it) and since these lasers are starting at 200 mW, I'd assume that he knows what he's doing and has met all the safety precautions.
@xXHowsthisXx mW is a term used in physics and electronics. It is short for milliwatt, or .001 watt.. Wattage is simply the output of energy, whether that energy consist of light, heat, or sound. In this case, its light. The higher the milliwatt rating, or mW, the more energy the laser has.
can i plz have one of those lasers? I would really appreciate if u could respond back. I really want one but i can not get all the parts. Thank you for your consideration!
@styropyro The driver run to me for a max of 350mA.. and also, to much on the driver will kill the diode.
With the video of old computer parts, how much voltage and current did you give the LPC-18?
BTW, the micro rckstr driver is no longer sold :S
I would love to see you attach a small burning laser to a drone and take out some ballons please
Somlith Souvanlasy he didn't use a drone, but he does have a video of one on a cheap R/C robot
This on the other hand doesn't apply for European countries, as we do not have the rights to possess arms unless it's associated with your profession or potential deployment.
Point being, this is an easily accessible weapon that isn't illegal in Europe.
No, no license required, but I can see license in the near future. Also, 3 watt red lasers isn't something you can get your hands on so easily, it'll probably cost 5,000$+, not something the average idiot is willing to spend on a laser.
900,000 years later "9,999,999,999,999,999,999,999,999,999,999,999,999,999w can disintergrate anything in its path, go through everything and make a hole through the universe if it doesn't destroy it first (destroys the universe in 0.0000000001 attoseconds)."
@Themandudebro227 I Buying A 200mw Burning Laser , But I Don't Know Is It Really 200mw . The Burning Laser Model Is :Astronomy High-Power Military Green Beam Laser Pointer Tactical Pen Professional
Help Me Check Out For The Out Put . Thanks .
@97221135 ok, first lets define a burning laser, its just a laser that can burn right, any mW laser that can burn is a burning laser, if you adjust the lens, find the thinnest beam spot, on that spot, you can easily light a match, like what i did on mine..
Just bought a 200mw Laser for the lolz (i love pay day)
Is there any tests I can do that will prove its a 200mw to myself,
The Laser was very cheap and I just want to know (bragging rights to my mates who have 5mw laser's)
Pleaseee Reply!
sorry i dont know much about these things..... but doesnt haveing your hand that close to a laser beam (thats bein interupted).... kinda subject your skin to light intensities its not ment to handle? :S ( just askin coz i dont know these kinda things)
Why don't you do test loads in your videos?
if I would see just your video and try to build a red laser I would kill my diode.
Thanks god I went to LPF before building my red... you should show test loading to your audience.
Don't give advice without knowing the actual answer.
The laser laws vary by country. In most countries, you can own them. In the U.S. specifically, you can own all of the above lasers in this video, and more.
Dragon lasers is shit.
WickedLasers is clearly superior in quality and is much cheaper than DragonLasers.
1Watt laser most certainly lights a candle.
Lol, even a 30mW laser makes you feel a burning sensation.
So just watched some of your videos, very fascinated and would like to learn more about "Laser Science" if there is some where you could start my journey off with that would be nice.
and no i dont just want to burn things.
wrong, if the wall was a mirror then light is reflected in a specular fashion, but the wall (which reflects in a diffuse manner) regardless of color will heat up. black walls (bad idea) would retain more heat than any other
Hey, I got a green laser pointer and it's written on it 500mW. It doesn't do things like you said in video. It doesn't even light a match. Is there a way of improving it's intensity. I've heard something about LPM what's that?
Not true, "burning power" relies on the power outage of a laser, not so much as the wavelength. The wavelength of the laser decides what objects the light absorbs into and what objects the light reflects off of
let me guess, you got a green laser from some random website that claimed that it was a 300mw for 50$. well.... that laser is probably no more than 50mw in reality. A real 300mw green laser would be around 500-1000$
you can buy lasers of any power pretty much. Some colors cost more than others because of the different process they go through. For example, a 5mw red will cost about 3$ while a true 5mw 589nm (yellow) will cost like 300$.
in all honesty... have you ever tried to light a cigarette with one? I'm gu3essing it would work due to the whole lighting paper and cardboard on fire thing, but still... it would be bad ass to have a laser cigarette lighter.
Different wave lengths will be able to burn different colours for example a 500mw ir laser will only be able to burn very darkly coloured materials were as a UV 405nm laser can burn lightly coloured materials and darker ones too
@jerryk2198 Sorry, i was in a really bad mood, what I wanted to say before I went off, is that sunglasses would do nothing, soooooo sorry. I do play with lasers all day, sorry. anyways, Just fair warning, never use sunglasses
