Use for dead green lasers? IR?

[IsaacT]

What if you had a green that died, but it was just the crystal alignment. Since the greens are made from pumping a much more powerful IR diode, couldn't you take off the crystals and turn it into a powerful burning IR laser? Personally I would much prefer the beam visibility aspects of the greenie, but if there was no way to fix it, would turning it into an IR laser instead be worth it?

If it is just the crystal alignment, you may try to correct it again.
Or you could make a 635nm pointer with a baby LM317 driver.

You could make into an ir laser of you get the collimation correct. If you want an ir laser. You could also use the drive and attach it to a red diode if if the current is adjustable.

What?

You do know that diode inside is 808nm, right?
And that doing what you said, is basically building entire laser anew, except for recycling old host?

And since you're alraedy building anew, might as well go with new green module or powerful red LCC/LOC build, or bluray of prefference, or hell, 445nm ?

I've got about 10 different crystal sets from a bunch of cheap greenies.
The other parts get used in other projects or I slap beefier crystals on them.

99% of the time, when a green laser dies, its due to a pump diode that gave up and not the crystals.

You are right. I forgot the green module is different from the normal laserdiode module. If that was a red pen he could just swap the diode and adjust the current.

I don't actually have a broken greenie, just wondered if it would work, lol. Thanks for the replies

Well I broke the crystals (well the disc their in) glue that was holding it to the pump diode on a ~30mw and was able to screw the culminating lens in far enough to get a good divergance 808nm laser (using cell camera to see the damned thing) and focused right it can pop a sharpied balloon. You can see a tiny red dot where the laser is hitting when focused but I try to use my cell to block it from my eyes.

It's all cool, Blord. We're here to learn

ExtremeOdd, I'd reccomend against playing with IR until OP has a little more knowledge... and some good IR safety goggles for maximum protection.
