Since you are much more experienced, maybe you could answer my question (about this particular build) - with a YAG laser of this power Q-Switch is necessary or it would work properly if I attached right mirrors? And at this power mirrors should be water-cooled and thick, right? I could get...

Yea, I am only looking at it (and reflection, scattered or not) through my phone camera

In order to test these diodes fully I need to supply at least 10A. Since I dont have regulated power supply strong enough for that, can I just use 3,3V line from ATX PC PSU? Or is it too 'dirty' (spikes, transients) and will kill the diode? EDIT: Nope, doesnt work. When I try to power up with...

Yes, it looked almost exactly like this. You can bid with confidence. I paid 100$ for it tho Anyway, probably gonna dismantle this one for diode bars, buy next one and try to power it up as a whole. Would probably need Q-switch for it tho, no internal mirrors Also there are 4 42v 50A modules...

I bought an unknown (used) laser head from local site. No info no datasheet, it turned out to be a high power diode pumped YAG laser. Look what I've found inside: Large YAG rod in flowtube, appears to be in perfect shape Diode compartments Opened one I'll have problems with testing...

Okay, I might bite that offer. But first I'd like to ask some guru an important question: I know this is a diode laser, no doubt. However - how big is a chance that I will find inside 808nm type emitters (and maybe a nice YAG rod too), no matter the mount/case style? What is more probable in...

Imho its a diode stack, cause its made by dilas. Also the operating voltage (42V per stack) is consistent with 20 IR diode bars in series. I am almost certain the diodes are shot though. What else I can expect inside?

I found an interesting offer on my local auctioning site. Can anyone tell me what the hell is this and is it worth buying (for like 150$) - only things specified are: this is a laser, and it has over 1kW output power (no wavelength info). If diodes don't work (which I assume is true, too cheap...

By the way guys - I am in need of C-Mount 808nm diodes from 2Watts UP that I'd gladly buy from you if you have some left (slightly used would be best cause probably cheaper than new :D) , or even better trade - I have tons of miscelanous laser stuff you'd maybe be willing to trade for some 808...

So it doesn't only happen to me? :san: Well, I've decided to leave this diode in a sealed bag and wait until I buy nice soldering station and learn to use it - then I might practice on some dead diodes and finally fix it. Maybe Alaskan is right but I too have doubts about 4.5A flowing through a...

Yes I do. The negative lead is completely gone. Since soldering isn't an option because I'll fry the diode before solder will stick to this almost unsolderable surface, I was wondering if Ag based glue for trace repair would work - I could buy this easily. This is not the first time this...

What is the best way to attach a broken negative lead in C-mount diodes? Careful soldering or some kind of conductive glue? I accidentally broke of negative lead from high power 808nm IR pump and I need to get it working again. What are your methods of dealing with this kind of situation?

My 2211 head is a little bit newer than this PSU (has one 22 pin connector instead of two smaller ones and a digital hour meter) but they should be compatibile. The big problem here is that I can't really buy an argon laser PSU because I live in Europe and shipping from US is prohibitely...

Hello I have 2 argon laser heads, one NLC 800 Series (quite large) and one Uniphase 2211 (in very good condition, got it from local auctioning site). Unfortunately I can't do anything with them since I don't have a proper PSU. I have an argon laser PSU from scrapyard which is somewhat working...

Yes, the pump diode is okay. I am always looking through camera (to see IR properly) so eye safety is not a concern. How to know if crystals are shot though? The main allignment problem is the fact that I dont have tools that allow me to move crystal assembly with 0,1mm precision. Unfortunately...

No way I am doing that, it would cost me more than I paid for them

Hello I have several EXTREMELY misalligned CNI lab lasers (532nm) - crystals and all stuff were taken out and placed inside again - they unfortunately dont work because of that, and I am completely unable to allign them by hand, it's just so damn tedious. Can anyone tell me how to do it...

Yea I do, but I am not really interested in pointers, rather lab units and laser show projectors. I have a lot of stuff for building them

Taken from rgb laser show projectors to be swapped with 635nm ones. Diodes were taken from casio A145 with bad pixels (broken dmd chip)

The problem is I have no idea how much those are worth. Thats the reason I didnt include price
