I will pay shipping, let's say that was a misunderstanding

I was under assumption that you keep it and diode's worth = shipping cost? Idk, here it's cheap. If I was wrong then correct me, I mean no disrespect

I can send a diode for free (just cover the shipping) for anyone able and willing to do some tests

I have a lot of unknown laser diodes from viatoll system cameras (basically, their job was to scan the plate of passing car), they are IR most likely. Couldnt find any info about them. How can I get the most info, destructive testing on a few of them is fine since I have a lot. Can they be...

Do you still have it? It'd be good for reviving one of my old projectors

Forgot to say that its actually a diode laser, not argon.

There is a coherent 488-20 laser on my local auctioning site with mainboard, in working condition (at least the seller says so - I'll need a proof anyway). Is it a good deal?

Wow, thats a great piece of information. I have a question, though - arent 3w and 5w versions the same thing? Even their pump diode currents are so close - they may be using the same diode. How much power were you able to get from your unit?

It was a moderately-cheap chinese soldering station (not the cheapest one, average) with temperature regulation. Works well for my uses althought not nearly powerful enough to solder brass module directly to baseplate (tried that to improve cooling, far better than thermal paste and screws...

I fixed it. After many failed attempts I decided to do a nuclear-soldering-option (I was pissed off and I didnt care if I break it or not anymore). Surprisingly, it worked, and diode works well and still holds rated power (althought operating voltage rose a bit, maybe because my solder joints...

Okay, since the TEC problem is somewhat solved, I have another question - I have a CC psu for jenlas but it doesn't support modulation. Is there a schematic for a 'modulation dongle' I could insert between psu and the laser head that would enable me to modulate the laser via ttl or analog? I...

Hello I have several medium and big dpss lasers that I am going to use in my RGB projectors. Unfortunately there is a problem - I have no temperature controllers for TEC cells and when I looked up their prices I was shocked - they are ABSURDLY expensive and I am never going to pay almost as...

Safety interlock (key) may be turned off

Hello Red laser modules in my RGB projectors have beam correction (cylindrical lenses) - as you can see on the photo, more than half space of the lens is left unused. Since lenses like that are even more expensive than diodes, I was wondering if I could somehow cut them in two without breaking...

Hello Is anyone here (preferably in Europe) willing to reallign my 532nm 1W laser module for a moderate price? Component placing is completely busted (cause it was dismantled) and it doesn't lase (parts are totally fine though). It is a Z-fold type cavity so I gave up on doing it myself - I'm...
