BluRay Laser burning things. 120 mW

120mW BluRay laser. It needs a heat sink, proper connections, and a case. It has an input voltage of 12.4. Be careful with lasers and always use proper precautions!

did you fog your room? thats a BRIGHT beam!

@juniortore1

No fog used. The 120 mW came from a 9V battery. I later found out that this setup with the AAA's did 160-180mW on average.

If you look at the laser do you go blind? im not talking about pointing it in your eyes, just looking at it

[jayls5]

No. I avoid looking at it when it's focused for burning, but shooting it a good distance in infinite focus isn't too bad. In either case, it's not going to blind you. (Think about using a magnifying glass as a kid anyway, that's many watts of focused energy that didn't blind us)

The nice thing about this color is the fact you don't really need expensive laser goggles. Standard sun-glasses filter this light if you're worried about it.

HI,

Are you driveing it at 130mA?

It seems you have the same that me, the housing looks the same, i did the lm317 circuit and works very well, i calibrated the current with the ampmeter to 110ma and keeps cool, just heat when you have it long time On.

Does yours need heatsink at 130mA?

[jayls5]

This one isn't my driver, but I don't think it uses the lm317.

@jayls5 Niceee, I thought violet lasers didnt have a bright beam, like red lasers since they are on the edge of what the eye can see. But violet is still a lot brighter than red! I cant wait till I get a working PHR

my freind picked up my laser thinking it was a cheap 2 dollar one u buy at walmart and he put a 400mw laser on my back ouuuch@@@

@blueblade50 Only 445nm lasers can do that. The 445nm wavelength is particularly damaging to your retina, as it bleaches photoreceptors instantly and permanently. If you just look at the dot of a 1W 445nm from within 30 feet, you will cause permanent damage to your eyes.

No worries. Thanks for your replies. It's a shame you and your friend stopped building those drivers... seems to be quite a lucrative business at the moment. I do have the rkcstr schematic and I'm eager to try building some... however, there are some newer drivers on the market (from Germany) that provide soft-start current ramp-up and down to increase laser diode longevity. Thanks for posting your vids. Cheers :)
