|    193nm Q-switched Yag system    |
|    04 Jan 19 03:28:46    |
      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...              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
