DPSS laser crystal quesion?
I was messing around with my older Crystalaser branded heads, in the last month I have two dire for different reasons and playing around with them I found the crystal assembly at fault, it outputs a very dim multi mode beam, I confirmed it was that section as I put that into a different head and had the same problem so I used it's pump diode to fix the other head. but I am wondering why it failed like that, what goes bad with the crystals on a laser that only outputs 25mw?
Can the crystals be visually inspected for this?
I don't know the power of the pump as I have no data on it, looks like a C-mount but the beam is inline with the mount and screw
Thanks
