- It is time to test the strongest lasers in my collection, now that I have both a laser power meter and spectrometer. I can test both power and wavelength of the strongest laser for each laser color I own.
I have 11 colors in my laser rainbow, so hang on for an epic journey into the lasers in my collection. Many of which I haven't shown in a video before!

I wish styropyro would see this, and he would be " Hold my beer".
He probably has the most powerful hand held laser in the world
@@Kitchen6419 at least he had at one point but I Think he dissasembeled it for parts.
Yeah I thought of his tattoo removing laser that was over 1 megawatt pulsed and strong enough to destroy the CCD in his camera with indirect exposure.

NOPE gaming why thank you. The artist is QuinNSFW (something like that, and yes, it is nsfw)
where can i buy this laser
This video was total nerd fuel, I love it.
Thanks! My enthusiasm for lasers is definitely on an über-nerd level - as with many other science subjects x)
@@brainiac75. Same here, I'm sort of a laser Collector/enthusiast, I have about a 100 of them.
Everything from about a few miliwatt, all the way up to 2.5 W focusable blue, that will ignite cardboard instantly, especially when focused, When focused it will ignite steel wool.
I also have a 500 milliwatt laserlands green lab laser, that is no slouch either.
Just recently added a one Watt green laser to the collection.
styropyro : laughs in 200watt
Yeah, he certainly has me beat on all wavelengths... But hey, I have my neodymium magnet collection too ;) Thanks for watching!
@@brainiac75 You tell'em Braniac!!.....Also tell 'em we hear faint evil laugh and soft voice from a lil skinny guy that's always saying,

I love how he uses cd cases and clothes pins along with all these instruments in his tests, it gives that homemade touch. Thaks for the video!
Thanks Joseph :) I am still an amateur though my equipment may be getting more professional over time. Clothes pins are so useful - featured in many of my videos :D
@@brainiac75 it's kinda cool though, i love lasers their color and your video is just awesome i really liked the video you earned an sub from me
I have a Wicked Lasers Spyder. It is terrifying, and I am so glad it has a code to turn it on. Most people do not understand how dangerous these are.
The spectrometer you are using uses Toshiba TCD1304AP linear CCD sensors. It has extremely poor sensitivity above 1000nm, and almost nothing above 1100nm. For this reasons, you need to calibrate it first. One of the better option is to use incandescent light, fit in the Planck's law distribution, and use that as a calibration. It will help a lot, but will still make upper end of spectrum noisy a bit. I am not sure if the software provided with the spectrometer allows doing it internally, but if not, it can be done using external program, or even a spreadsheet.
I was about to drop a styropyro joke, but after reading the comments, I believe I was not the only one so nevermind. Great video
You can drop a Zenodilodon joke :P
Hehe, you sure have me beat on most wavelengths, Zenodilodon. Love your channel by the way. Makes me want to get into DIY laser pointers.... Thanks for watching!
@@brainiac75 You have an excellent channel yourself! I am trying to work out of laser pointers a bit, I want to get some serious hands on optical physics work going, there is so much to learn still. My goal is to eventually make some crazy laser heads and get into more advanced things like custom SHG/THG. Honestly I kind of find pointers boring as you can only really collect colors and burn things. Currently I just want to help others get better with working with laser technology as I found it really difficult to find good sources when I started.
I love your videos ♡ always so calming! :)
Thanks :) More to come!
When a long time ago I worked in the paper industry, I read all kinds of articles about really powerful lasers used or tested for paper (and other materials) cutting. I particularly remember that some people tried how thick packs of paper they could use. They were talking about kilowatt level of power in continuous mode. 10600 nm wavelength CO2. I never was dealing anything that power levels. My experiments were limited to some angle finding using helium-neon laser. Later on, diode laser pointers emerged and I bought a couple of them -- still have both!
But the real reason for my comment is that at one time I was involved in an attempt to measure, and potentially control the paper web moisture content immediately next to the dryer cylinder. The idea was that measuring the water vapor content would tell the paper web moisture content, or at least tell something about the moisture variation. And somebody had an idea that to be water vapor specific, you would start with water vapor laser. Of course. Sad to say, we were a bit amateurs and did not have a matching wavelength detector available. It appeared the laser probably worked but our broad band receiver saw all kinds of wrong phenomena.
Styropro be like nah..!
Oh, yes... Styropyro must have me beat on any and all wavelengths x) Thanks for watching!
Ahem 100w cow handheld laser
@@brainiac75 No worries Magneto-Brainiac!! Sith Styro cowers as he hears that evil laugh from Emperor Photonic.
styropyro only beat him in doing utterly crap with very strong lasers, like putting things on fire, blowing up stuff, popping balloons, etc... I know styro from LPF forums and he a great person there, but his YT videos are utter crap IMO. and complete lack of the actual fascination of lasers from an adult and mature perspective..
it's a pupe-fetich seeking the lowest common value of yt-clicks from mainly the very young pupe-crowd by doing stupid stuff with high-powered-lasers and blowing stuff up, and it ain't really young kids you want messing with high powered lasers. and its acts like that give lasers a bad rep. and likely also why makers go out of their way to make these high powered DLPdiodes not available for the public, not least hence these new multi diode-arrays where even spec sheets it hard to find and close to impossible to separate..
@@JAKOB1977 what do you do with your high powered lasers?
"Klick like to celebrate it with me" 😭 yes I will😌
Awesome! Party has begun :D
Very interesting channel! Thank you for making videos!
ALWAYS remember guys, these lasers are no joke. And many of these can instantly want to have a rewind button in life.
I always try to leave warnings on laser videos because it's one of the most deceiving things to people who have no experience with them beautiful light that can put your eye out faster than you can blink literally ! :)
@@christopherw2233 ur a good guy
@@MP-tz2yn it'ss hard to find people in the world who actually care about each other sadly.
@@christopherw2233 true. You do a good service putting the warnings, the dots look so innocent - I had to do some reading myself about it and was shocked to find how quick it can blind you
Lasers have always scared the shit out of me. Not like, viscerally, but with how often I get those sort of dangerous intrusive thoughts, I know I’d just end up blinding myself.
It would be so easy, in a couple of seconds, bam, no vision for the rest of your life.
Not to be unkind, but you seriously need to get help. Good luck.
BRANIAC:-" I GOT A 1.5 W POWERFUL LASER"
STYROPYRO:- "MAKING IT MORE POWERFUL"
wow ... great video thank you much 👏
Since you asked... I've got you beat on the blue laser, mine being the 2W version and the calibration sheet showing ~2.5W. I didn't really believe that rating at first and thought they were probably inflating the numbers a bit, but after seeing how close yours was, maybe it actually that stong.
Also, a faster way to get the max power setting is hold down the button while powering on, then when you press the button it is on at full power, and shuts off when you release it.
Styropro made a 100 Watt laser a few Month ago.This is just insane.
You totally make the infrared spectrum sound sinister with the music. Love it!
I always enjoy your videos for the longest time, and have help a lot to become more aware with quality of laser pointers and the dangerous fun with magnets!
Glad you like it! I often spend quite a time finding the right track and timing it to the video content. Especially the Hercules chapter took a while just for editing the music track. Thanks for watching!
@@brainiac75 How did you figure out the diode they use for their lasers???
@@brainiac75 I mean sanwu lasers*
Great stuff! 👍
1052nm is a weaker lasing line of the neodymium. These crystals can lase at many different frequencies and at many different efficiencies, but they can fight each other for gain. The "correct" line is chosen with a dicroic coating on the facets, but these coatings aren't perfect. Sometimes other lines sneak in. I once had a green pointer that lased at 532, 537, and 542nm simultaneously presumably due to a coating defect.
I remember the first time I saw a laser pointer. It was in the 90's, it was already the keychain model red one. I was inside some kind of small mall and saw that red point fast on the floor, my first thought was that it was a cigarette butt but then the guy showed in his hands to some other people, everyone amazed. Now it is so common but still something awesome.
I thank you Bro, fantastic job!! I appreciate you 🤗🙂
Great video!
I've had a green laser similar to the pen laser you showed for about 12 years now. I just bought a 445 Blue Laser but I rarely use it. I'm not only afraid for my eyes but also for my 9 yr old daughter's eyes. I bought two sets of laser protection glasses but not 100% sure they are the right ones. I mentioned two rangers with a gap between the two spectrums.
It would be nice if someone would do a video on the different ranges of Laser Safety glasses and which laser light they protect against.
Nicely done sir
GH05030C2LM(or newer model GH05030D2L) is an amazing while troublesome laser diodes. it's mint green is one of my favorite color, but as I have get several of 10 this diodes I found the actual wavelength of individuals are so vary that can be result color from malachite(510nm)
The only thing I can guess is that you had some neon nearby that got excited by the intense 532nm laser light. Maybe an exposed He-Ne laser tube, or even some gas-discharge tubes with a penning gas mixture inside?
the 1152nm peak is a dpss line that you can get with some self frequency doubling crystals like nd:svap and yb:ycob, it is a pure yellow when frequency doubled at 575nm, i have a 575nm laser using that process
i also have a half watt green laser, and in addition an 1 watt blue laser, but my favourite is my E3 wicked lasers green one laser, who often still use... great video btw!!! (i wish i'll buy the sanwu laser power meter!!!) happy new year!!!
No really high power lasers, but I love the 488nm ones and have built 2, both underdriven to around 30mW and a nice direct injection green diode at 515nm and 15mW. One of my 532nm DPSS lasers leaks around 7mW of infra red.
What can you do to resurrect the oldest laser that was 4mw and is now only 1?
Any way to fix it in your home shop for a TH-cam video?
Much love my dude
I’m a studying laser technician an perhaps I can help you with what you’re seeing on the Hercules laser. I believe you are seeing what are called longitudinal modes aka standing waves. These are wavelengths of light that are able to exist in the laser cavity due to the constructive interference of the way you laser cavity is configured.
Yeeesssss, you're back!

Nice Collection
Your videos teach me more science than my school
This TH-cam was very informative and helpful. Thank you for taking the time to share your knowledge and expertise.
Personally, I would really appreciate a TH-cam this thorough explaining about laser safety goggles/glasses. I am trying to make a decision about laser goggles but it is very confusing. Some lenses offer multi spectrum protection. Some specify certain types of lasers with certain spectrum specifications. And the question of power never seems addressed in a specific glasses/goggles specifications. With your range of lasers I am sure you must have solved the conundrum in which I am mired. Also, price is hugely variable. Just an idea for your research.
I love your videos Danskjävel! ❤️
Thanks, fellow viking x)
Informative as usual Brian. It is amazing about the IR leakage from the green laser range. Perhaps you could get some, preferably the Chinese ones, and test the actual mW and IR. I would not be surprised if some of them output Watts and not mW!! :) Cheers.
Thanks :) I measured one of my garden/decoration lasers in a patreon video, and it seems like half of the output from it is in the infrared.... That's so bad. I may make a public video on it, since I now have better equipment for showing and measuring the issue.
@@brainiac75 Wow, it has been a long time for me to catch up on things Brian. This reply from you makes me very nerveous about going forward. I hope people lean from these comments. Cheers.
I love the music with the HERCULES.
Whats the most powerfull laser pointer i can buy in uk 2w? What one would u recomend i see wicked lasers ship a 2w to the uk
That smile your sporting is almost as big as the monster sized laser you have there! #supperstoked
First time here, i keep seeing people disable lights and cameras with these from like a few yards away and got curious which watts would do that and what (if any) level makes it refract off of the glass
Hello Brainiac, i love your channel, thank you for the very valuable information that you share in your videos, i have always be fascinated by lasers and i now own several of them, two are red dot laser levels that have made my shopfitting career so much more precise and easy to gain very accurate measurements on my own, i recently bought 2 laser pointers online, one is a green beam and the other is a blue beam but only the blue one came with specification data, the sticker on it claims a wavelength of 450nm and a max output power of 50000 mw and yes that's four zero's or in words fifty thousand.
Is this possible? and how does it compare to the ones you have just demonstrated??
Thanos 5w is my most powerful. Havent used it on a spectrometer, but labeled as 445nm and color seems correct enough... friend has the power gauge for it (why can I not remember the technical name?) But the 5w laser was actually putting out 5.7w on fully charged 26650 batteries
My kind of dude,he celebrates his lazers birthdays. lol Some badass lazers man.
The dramatic sound effects had me dying at this nerd jargon... And intrigued.
Lots of 808 and 1064... Oh NO!!
what are the best visible lasers for cold weather? i have a 5mW green one that performs like shit on winter here in Spain
nice Video thx. I ve a very nice 50mw Viper Laser from Dragon lasers with a Wavelenght of 637nm. The dot is nearly round and its very visible for a low power red laser. Beam Divergence is < 0,5 mrad.
Damn that HeNe laser has a clean output, they sure don't build em like they used to
what a difference a couple years makes. ~5w blues are all over fleabay now. At under $200, I just had to grab one. I paid a little more than average for the 465nm. Now to wait for the slow boat from China!
always like your back ground music,it so works
Thanks! I went through a lot of tracks until I found just the right one for the Hercules chapter. It fits the mood I was experiencing just right :)
@@brainiac75 you make the right choice on all your videos having seen them all thanks
What a great beautiful science channel ! I've always watch some videos from it when I'm bored, or just to warm up the 4200lm halogen lamp on my InFocus projector. It has some DLP technology too ! I'll love to see Brian talking about DLP technology in general...
Edit : And... Maybe do some weird experiments with DLP chip.
Happy holidays
You are a very cool guy :D
Very cool detector
So good it's a shame it ended. I used to work in a facility which made lasers for communications, some of those go towards the long end (or beyond) of your new power meter. You can sometimes pick up those on eBay for very little, do a search for something like Nortel Laser. They are not hugely powerful but some can be wavelength tuned.
Thanks :) Some of those Nortel lasers do look interesting. Wavelength tuning would be nice to experiment with.
Where do I go to buy a good green laser pointer? I use a Dragon Laser (supposed) 300mW Spartan. But they stopped selling through covid. Any recommendations for a GOOD green pointer?
Meget spændende video. Mange tak :-)
Velbekomme :)
love the slightly ominous music making it obvious how dangerous these are
Have a 40 watt laser at home, though haven't measured its actual power output....
But its a CO2 laser tube used for cutting and engraving applications. And CO2 laser tubes are fairly cheap for their power.
I got some old tube lasers used at sawmills. They are like glass baseball bats. My dad use to repair them.
around 6 years ago, i got my 1.5W 635nm red and a near-4W 450nm blue stolen from me. Few years later and i now own an 11W+ blue that i built, a 1.6W 520nm, and a 300mw 488nm as my three favorites. I'm also planning on building a 50mw 505nm into a pen housing along with a 3W+ 405 that is going to use two diodes, just like my 11W build. I'll edit this in the future and discuss how it goes.
Nice collection! Hope you have a fire extinguisher at hand ;) I really need to try building my own. Great value for money.
I wanted you to do those Laser 303 and Laser 301
but good effort!
The last time I bought a laser was almost a decade ago with the generic 303 532nm laser.
Now I discovered about the Sanwu pocket series and want to try either the 588 or 592nm laser!! Its amazing how laser technology has advanced in the last decade. Also, will be getting proper safety equipments this time.
Sanwu doesn't sell yellow lasers you know.... no 588/592 from sanwu
@@bitonic589 i think i mistyped back then.. should've been 488s and 492s.
Just curious, what was the reason for blurring out the serial number on the Spider III?
I love lasers. I have a laser pointer which is black with gold colour focus and a gold coloured battery cap at the other end with a pen clip on the side also gold coloured. An old boss of mine gave it to me, he said it cost 80 dollars back then probably in the 90s. still works.
Nice, sounds like a collectors item to me over the endless black/silver laser pointers available today. Continue to take good care of it :) Yes, laser pointers used to be very expensive. I paid around 500 DKK (~$75 in todays currency) for my first
the diode in dilda 200mW red should be Mitsibishi ML101U29 or equivalent, while I am wondered why 2x3V batteries are used: use 6V input to power a laser diode driver that drives a 2.35V diode? as I know virtually all red and infrared diodes have Vop not larger than 3V
Whoa I think I had the same laser as your oldest, but mine was anodized black
hi. mate please explain how d you measure power per wavelengh? and how to see a light spectrum. many thanks.
Sir, from your experience. If u got same type of the laser but in many variation color. Between RED, PURPLE, BLUE, and GREEN. Which color is the strongest resistant?
I means can burn fast n more hot.
Thanks sir! ❤
Missing yellow laser get one! Good videos💪
A yellow laser sure is high on my wish list. They are just so expensive and inefficient :( The show laser will make a strong, yellow looking beam though. It is just not a true yellow laser... Thanks for watching!
Nice video, i got the same Arctic laser from Wicked Lasers, i bought it as a 0,7W and when it came with the test sheet, it peaked at 1,47W. Did you also buy the 0,7W or 1W version?
Hi Rasmus. You got lucky with that Arctic then :) I bought one that was specified as over 1 watt - not 0,7W.
@@brainiac75 That's kind of annoying to get a laser weaker than advertised. Wicked Lasers make some good lasers but there is a lot of controversy wether people are actually getting the laser they buy. Sadly i don't have a power meter to see if the 1.4W is true, but it can easily light up a match from 20 meters away with no extra lens to focus the beam.
You should definitely do a collab with styropyro! 😀
I have a Keychain laser, a powerful pointer pen laser, and a Laser 303. The laser 303 power is between 60 and 200 milliwatts and takes some time to burn a match.
The background music made the leakage very intense :P
What is the name of your optical spectrometer model? I've wanted to find something like that for a long time!
I've got a few 445's, starting with Arctic as the weakest and all the way up to the 100W monster that I'm almost done building. also have 900mW 405...
I'm currently making "eye-safe" 488/505 nm lasers because they are so beautiful but unfortunately very dangerous as soon as they hit the lasing threshold. so PWM it is. Am I correct in assuming PWM lasers with average output
I have to be very careful with calling lasers "eye-safe". Especially, since I am not an expert in pulsed lasers. Pulsed lasers are typically measured in joules per pulse and pulse width - not mW. You can calculate the OD needed for safety glasses here: www.lia.org/evaluator/od.php on the tab 'repetitive pulse'. The higher OD needed, the less eye-safe the laser is :)
The battle has begun... Styropyro vs braniac75
1:10 "Dilda"? What an unfortunate name for things looking like this ;D
Hehe, I think it was nicknamed Dilda for that very reason ;) And ILDA is a standardized interface for show lasers, so a fitting nickname indeed.
Not my field of expertise, but would you get a bump in infrared from any heating effects from the lasers?
You would. I just think it would be a more wide 'plateau'. Not a narrow peak as the shown. It is still a mystery find to me :)
Its good to know I'm not the only geek obsessed with lasers. I once had a boss tell me he would fire me if I said laser one more time after spending the better part of a week talking about lasers.
Is there a way to check the wavelength that glasses block to be sure I'm safe from my lasers? I have those cheap 1000 line linear diffraction grates...but none of the electronics featured in this video.
The glasses are stamped...but I would like to confirm myself they actually block the wavelengths they say.
If the glasses are stamped with the OD for wavelengths it is a good sign. Cheaply made safety glasses don't bother with this. Are they from a reputable brand and did you pay a significant amount of money for them - that are two good signs too.
But actually measuring their ODs is tricky. It can partly be done with a spectrometer like the shown, but testing for high ODs requires an ultrasensitive spectrometer or firing a strong laser at the glasses - potentially ruining the glasses.
Last year there were a couple news stories about a new handheld Chinese laser weapon for their army, do you have any info on it or was it fake news?
I have a blue 1000 mw/450 nm laser ,I just bought it ,i adjusted the focus on it and it might just me being obsessive over the laser cause that's how I am,always trying for perfection. Anyway I noticed or think I noticed for the first time,the laser is a rectangular shape I can focus it but it defuses after about 15 feet an the beam isn't staying as sharp at and after that distance,but it's still pretty tight an powerful,its just that rectangular shape and the power loss ,is that normal for most lasers ?Am I just being.too much of a perfectionist?Or does it.sound like to you that this is a damaged laser?.If it's normal sounding to you,the amount of scatter ,then can I buy anything to fit the tip,that further focusses the beam?Any after market parts you can suggest would be appreciated. Again I think I'm just tripping ,but.maybe I'm not ,well its bothered me enough to text you about it.so maybe my brain just caught something I didn't realize while it was changing on me,a change I suspect may have come.when I adjusted the focus the first time,I was gentle and it focuses fine, but it's just a tight narrow mini-rectangle now ,which isn't a nice dot,is there a way to focus the beam at 30 to 40 feet and keep a tighter beam to spend the lasers power down range as if I was only ten feet from said targets??..Again ,thank you for your time ,I know I wrote you a book here ..lol...but I wanted you to have all the facts .Yea I would love to know that it was probably like this from the factory and there isn't some thing that happens to lasers if you dont so "this" or "that " before focusing. ..lol...but give it to me straight,I'm worried that I didn't do something right an its damaged ,or is it just normal?
I'm considering getting one for self DEFENSE but not sure how good it would be for that. How long does it take to burn your attacker and neutralize them?
What are the glasses you use and where can I get some?
Yes, some green lasers output some infrared. I’ve got a blue laser, it pops balloons.
I used a Class 3b laser for an extended period of time for lighting a pipe. Can my vision be saved?
Is there a way to convert the wavelength of CO2 lasers? Like they do with the green lasers? Wouldn't that be crazy bright???
CO2 lasers are incredible strong (and bright), but their 10600 nm infrared light is so far from our visible range. I don't think we have technology that can convert 10600 nm infrared down to the visible ~400-750 nm range. Would be awesome though!
Awesome video. I really need a better LPM like that and would love a spectrometer like that.
Lets see from my collection the only that that "beat" any of yours is my home built 445nm that comes in at 1.8w. I kinda want to build another for "more power!" but 445 is kinda meh to me after the initial novelty wore off. I also have a red HeNe that's nearly a meter long that puts out 20+mw. That thing is a beast.
others wavelengths in my collection:
473nm (blue DPSS)
543.5 (green HeNe) both put out 1-2mw on my meter.
589 (DPSS yellow) 110mw after warmup.
594.1 (yellow HeNe) 2-3mw from both.
My multi-line argon is probably my favorite laser I have. At full power (10A!) it puts out ~150mw but that's from all six wavelengths it produces.
Awesome collection! Especially one of my dream lasers, the multi-line Ar-ion. But the yellow-green HeNe is also fantastic. So close to our eyes' most sensitive wavelength, 555 nm in daylight (507 nm at night).
9:46 He is starting to BELIEVE!
My favorite was the helium neon one.

Ignore the peaks from fluorescent studio lights

How much thick plate of metal can we cut by hand held laser so we don't need any gas cutter ?
congrats on the new analytical tools . great seeing all the new data .
Wish has lots of powerful lasers. I bought one for £30, don't have the means to test it but it is a blue laser about the se size and shape as the high powered blue one you used, mine can light cigarettes so it's very strong. You ahould do a wish laser review!
