FS or Trade: 50mW 532nm CrystaLaser DPSS Module

[300EVIL]

Hi Everyone!
Up for Sale or trade is two 50mW 532nm CrystaLaser DPSS Modules. Both units are in mint looking condition. One is outputing around 50mW. (sorry my power meter is on loan.) and the other is outputting around 1mW. Probably needs a new diode. If you want a quality AMERICAN MADE, Very Stable laser with a PERFECT TEM00 beam,,,,, THIS IS IT! Great for holography and other scientific applications.

SOLD!!!

Here are some pics....















Either one or both are available. Make me an offer via PM!
Thanks!

Here's what they look like inside!



Note the TEC cooled pump diode and crystal set along with the beam correction prisms.

I have one of these, it was really nice but the last time I used it my beam output was really really horrible looking, dunno what happened

maybe dirty optics?

also you can sort of TTL modulate these, but they seem to react poorly to it, maybe if someone could reverse engineer a bit of the driver it would work better

flecom, does it look something like this here:
Try removing the front "ir filter/colimating lens" assembly, see what it looks like.

Damn, that is trippy, I will have to try that on my other non-IR filtered head! I would recommend this laser, and would pick it up myself if I had more cash around!

Wow, that is trippy / beautiful! Just like the picture Adam has on his wall in the beam pics of those lasers.

ya it does actually, what does that mean?

It means that you need to give your laser a Brazilian wax.

I had one with the same problem, I fixed it by readjusting the KTP a bit... probably a little burn on the coating

note they don't have an hybrid cristal but separate YVO4/KTP, the YVO4 being held on the black plastic ring just after the wedges, with a focusing lens in front of it...

I noticed the original diode has no FAC lens and thus approx. 20% of the pump beam is lost in front of the first lens (first black plastic ring), so it might be good to put a cylinder lens in front of that lent, or using a FAC lens

I have tried to replace the pump diode by a more powerful one, but it seems it is not 808nm but higher, as these diodes don't produce green light when held in front of a small hybrid cristal

I'll drop more info about this when I'll have time to play with that a bit

a presumed dead crystalaser unit will also be the host for my 976nm laser diode and my KNBO3... so if someone has a CT-mount 976nm laser diode, please tell me, I may swap it for a C-mount one (making a new diode mount would be a pain I want to avoid)

these are high quality DPSS lasers, the driver is really stable and very reactive (fast temperature settling), so don't hesitate if you are interested
