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?

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...

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...

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...

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...

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?

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...

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...

I will be updating this thread with more items, I'll start with: 2 x CNI 650nm 500mW lab lasers with drivers - taken from working projector, in perfect working condition. Can send more photos and beamshots if you are interested. Selling both of course. Price - offer and we will see 20 Blue...

Hello I have some lenses and prisms from argon and he-ne pickup from IBM and Xerox high performance printers. They are quite specialized, most of them are cylindrical and rather BIG. I will send photos via PM if someone is interested, we'll work out the price (or exchange, I am open to that...

Hello I've found a NLC 600 argon laser on local scrapyard (I took it from high performance printing station), with PSU. Said PSU powers up and works normally, laser fans start ,but unfortunately it will not lase, current meter doesnt move, there is no discharge glow. Every 30 seconds or sth...

Hello I stumbled upon an auction with a disco laser made from military he-ne tube. On the photo it doesnt look red, can someone who knows better tell me which wavelength it is? LASER DYSKOTEKOWY zbudowany na bazie lasera z pojazdu wojskowego ! Bochnia ? OLX.pl Thanks in advance. If its really...

Hello I had CNI blue H series 473 laser (500mW) and I decided to change the crystal set for green one cause I need at least 1.5W green laser, unfortunately I can't allign it properly, no matter where I move the crystal assembly, power is AT BEST comparable to my CNI MGL 500mW, and the mode is...

Hello Lately I've bought a 500mW lab 532 laser (used) and I wasnt satisfied with quality of beam so I decided to take it apart for realigning. After some testing on the bare diode, I've come to conclusion that it MAY be much more powerful pump diode than needed, with limited current. For 500mW...

Hello I have some laser modules with drivers (and one with ac/dc supply) for sale, they were removed from rgb laser that I decided to upgrade. All in working condition. No price tags, just make your offer. No power ratings because I dont have a power meter. B200 405nm laser module with driver...

Hello I've wanted to buy an argon laser for a loooong time, unfortunately in my country I could never find it on ANY auction sites. I've found a argon laser psu though, for ~40$ - this particular model has outlet for interface but maybe it can be overriden somehow, and is it worth to buy this...

Hello I've bought a CNI 500mw 532nm module (with oem power supply for disco scanners) with 30 kpps galvos and showcard for around ~120$. Module is working fine, but I saw some day (on other site) people upgrading those particular modules to 1w, and even 1.5w 532 - as far as I know crystals can...

Hello I've found (on polish 'ebay') a blue module from laserworld 4000rgb, seller uploaded a video of testing this module. He used some CRAZY voltage (8.8v and 2A) and the laser didnt fail. He claims that this is 1.5w module but at this barbaric voltage 1.5w blue would instantly fizzle, i think...

I have a small (like 1x1x4) NdYVO+KTP crystal from (broken) 100 mW disco module, I decided to mess up with it for a while since I dont really need it for anything. I took my 2.5 W 808nm pump diode (REAL overkill, I know) and checked how it will work with too small crystal. Results are quite...
