IPG Photonics YLR-40 High Power Ytterbium Fiber Laser, 40W, 1080nm Class IV

Description

IPG Photonics YLR-40 High Power Ytterbium Fiber Laser, 40W, 1080nm Class IV
Used, tested and guaranteed in working condition. We set this to about 0.7 amps and it very quickly started to burn the board.

There is supposed to be an interlock, which we don't have. We jumpered the pins as pictured, but you might want something more permanent. We also rigged up a 5v power supply for the "Emission" trigger in the back, as pictured. It's not pretty, but it does the job and we're happy to send it along if you're interested.
The specs below are copied (and updated to the best of our knowledge) from a YLR-100 manual. Other YLR-40 units are listing their max watts at 50 or 100. This unit was able to go to 45 watts, but I don't know the actual power rating.
