Hello friendly sci.optics community.
I am fortunate enough (though in many ways, not so much) to be attempting to restore a very interesting Q-switched Yag system.
I'm wondering if anyone out there has some experience with such beasts.
I had it working fine but a relocation has changed that.
Temperature in the new location is around 5 degrees C cooler, so everything needed readjusting, but IR came good eventually from the flashlamp pumped source.
I can say the IR generation side is now OK'ish. Should generate 300mJ, I get 250.
The 532nm SHG output is low however at 20mJ.
No matter what angle I move the thing or set the adjustment, that's as good as it gets. It looks OK, clear path, no frosting.
So I was wondering if anyone has a good guide to testing and/or repairing harmonic generators generally as aside from adjusting them, I've never tried to seriously test and/or repair one. If indeed it has a problem, maybe I'm not testing it properly...
