    Default 40w fiber coupled 808nm Diode for CNC

    I bought this a couple years ago with the hope of mounting it on my CNC machine, it never happened. It has a red pointing diode so you can see where the beam is pointing and the focusing lens, It runs on 1.9V and about 40 amps max. Just supply 1.9V and slowly ramp up the amperage to obtain max diode output then back off about 20% to preserve the life of the diode, it needs to be cooled to 24C or less and has a thermister built in (that is the thin white wire). My power supply only goes to 20 amps so I have never had it to full power. I will take $250 ( the lens is worth that) for it shipped in the USA only.

    Would this thing pump a KTP/Vanadate hybrid crystal? (the ones with the mirrors already in place)

    When God said “Let there be light” he surely must have meant perfectly coherent light.

    It should, I took one out of a pointer and and tried it. It got very HOT FAST but I did get green.

    I'm sure I don't have to tell you this is very Dangerous if you hit your eyes thats it no second chance.
