one outputs between 200mW and 300mW and has its Nd:YVO4 replaced by one from a meditec laser head I had from junktronix for coating testing (it can be pumped by a 25W multimode pump) - I have repaired the TEC controller of this one by replacing the LF457 which as defective
the other outputs between 150mW and 200mW
both need to be correctly aligned and had their pump diode curve traced to check for pump health with threshold at 800mA to 900mA and top at 4.7A to 4.8A at approximately 4.5W of output power
drivers have some bent housings so I removed them and they are sold without it, but no importance for integrating them in another project or dedicated box is the best thing to do
they have integrated power supply and current/temperature metering
the one with the replaced Nd:YVO4 and repaired TEC controller is 200€
the other one is 150€
there is no guarantee except for the testing I have done on them which proves the diode health, and that the driver works flawlessly
keep in mind those are V-fold cavities and that you'll most certainly need an IR viewer or webcam to align them by viewing the spot image on the screen
I can provide instructions on how the alignment process takes place and what to do and expect
I dropped that project due to lack of time and funding needs for the coming baby

both are now on ebay at the same price of 150€ per unit, and must go ASAP ;)
