DIY Greenie?

Has anyone ever made a DIY greenie? What i am thinking:

1. Buy a 532nm green laser module from AixiZ
2. Pull out the weak 808nm IR diode along w/ the stock driver
3. Build a new driver, buy a 200mW 808nm diode, solder it together, and install in the housing with the pre-alligned crystal.
4. Now you have a powerful module
5. Install in Dorcy Jr. and test it out.

Anyone support me? I have had good ideas in the past...

Uh, no.

This won't work. Cheap lasers have cheap crystals. Pumping more IR into the crystals won't make much difference. Otherwise, high power greens would be cheaper.

It's the crystals that make them expensive, not the IR diode. Better quality crystals, better laser.

Ok, but i know someone who made a DIY 90mW with the crystal from a 5mW greenie.

Yes, i knew that. The crystal will get oversaturated. I just thought this because someone DID make a 90mW greenie from a 5mW dead greenie. That is why i was concerned if it would work.

were can you buy better crystals for a green laser that can go up to 200mW and would a 200mW IR diode out a dx true 30 get 100mW out the crystals

Maybe it was a leadlight.I'm just not seeing the newwish module reach 90mW, it probably has tiny crystals. :-/

eBay, or ripped out of another greenie. 200mW IR to 100mW green, no.We're talking about a ~20% efficiencly tops.that would be more like 40mW.

I dont trust ebay and what is the point of buy a 200mW green laser to take the crystals out to make a 100mW green laser?

I just wanted to add that the pump diode in the aixiz is probably close to 200mW to begin with, and just has low efficiency crystals. SO even if you DID want to try something like this, 200mW is not a big pump at all. Like switch said you're looking at about 20% efficiency, realistically it may be less. So even if the crystals could handle more power, one would want to use at least a 500mW pump.

Hey I was wonderin, if there is any devide accesible today with green laser diode? You can pull red offa dvd burner, blue off PS3, is there anything from what you can pull a green laser diode (except a green laser of course :D)

Please reply to my mail:
eudaimonium@gmail.com

'cause I don't spend too much time on this forum.
Thanks

No green in consumer electronics. It just wouldn't make much sense. All the other lasers in normal electronics (red, infrared, blu-ray) are diode lasers. Green are DPSS (google it) and would take up a bit more space. Not to mention that I dont think a green could do anything that a red or blu-ray couldn't so it's just not cost effective.

Yes, i know about the 20% effeciency, but i don't really want to build a high powered green laser. if im used a 500mW pump diode, that would give me 100mW. I could use a 1000mW diode, which would give me 200mW. But i still don't know where to get the KTP crystals...
