Something's not working properly! The crystal is broken!
Can anyone tell me where I can buy a new crystal, and what type I should have? Or even better, someone who can replace the crystal and adjusting it? It's a CNI module!

considering how dangerous these lasers are when open, i don't advice you trying to repair it without proper eye protection.
try contacting CNI. it may also be cheaper to just buy a new one instead of trying to repair that one.

What IS odd is how well-formed the central blob is, if that's 808nm. (I also think Absolom might be right, it's definitely CNI unless someone's copying their casings and internal details very closely, and it does look a lot like the innards of a blue one I saw pictured here a few years ago). But 808nm is focussed into a crystal with a short focal length, it won't make it out the aperture looking like that so far as I know, not even if its path, post-lens, was empty.
If this laser is about 100~250mW, then the cost of repair will almost certainly go past the worth of a good used one on eBay. And that's without the cost of goggles for 1064nm. The 808nm is hazardous, but IS manageable in a small laser, even without goggles, with a lot of care to sneak up on it from a moderate distance while viewing its innards through a camera viewfinder, but the central blob looks more like a malformed 1064nm or 946nm beam, and that laser had no IR filter, apparently. All is NOT well with it, if I had it I'd want a good copy of it just to know what that looks like before I did anything with this one. And that's speculative anyway, I'm not sure I want to get into the complexity of fixing a DPSS. The only cheap way is to use very tiny composite crystals that are fragile and difficult to handle, after that it gets easier, and a lot more expensive and dangerous as part sizes and powers go up.

Thats a CNI 532nm for sure. I have similar with a dead IR LD. Between our two units we can get one working.
