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!

BRANIAC:-" I GOT A 1.5 W POWERFUL LASER" STYROPYRO:- "MAKING IT MORE POWERFUL"

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.

Nicely done sir

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.

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.

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.

Missing yellow laser get one! Good videos💪

We have 450nm 120W now.

Great video!

That smile your sporting is almost as big as the monster sized laser you have there! #supperstoked

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

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.

Happy holidays

I wanted you to do those Laser 303 and Laser 301 but good effort!

Brainiac75: I have the strongest lasers! 10W laser cutter modules: Am I a joke to you?

Because you asked. I have a 1516mW 445nm laser. It’s kind of nuts so don’t use it often. It looks like yours, but runs two 123 li-ion rechargeable cells. And it doesn’t have the power ramp up modes, just on and off.

Very interesting channel! Thank you for making videos!

Much love my dude

HeNe gas laser usually also emit 1152 nm! it is just IR filtered. the 1062 wavelength is the default, which is frequency doubled here to emit 531 nm. check out the german wiki article for all possible HeNe colours! https://de.wikipedia.org/wiki/Helium-Neon-Laser
