CR:YAG 
  What would be a good ballpark figure for the initial transmittance for a cr:yag passive q-switch? This would be for a flash lamp pumped nd:yag laser with about 100-300J of electrical power. I know there is probably a lot of math behind it, but that is far beyond me. Regards.

Coherent Verdi Questions 
  Hey Everyone, I recently got a Coherent Verdi head from a friend, however it was an IR version, and thus did not have the heater installed, additionally, the OC mirror, which normally would be AR@532nm HR@1064nm in the green version, was a OC@1064nm. I got a new mirror from a green version, so I will be installing it with the LBO and heater for the system.... more »

Gain Bandwidth of Ne20 or Ne22 and natural isotope mixture 
  Subject line says it all. By my estimate, the pure isotopes should have a gain curve that's between 500 MHz and 1 GHz narrower than the Ne isotope mixture occurring naturally. This because the gain center moves about 1 GHz when the ratio of Ne20:Ne22 is varied from 0 to 1). Thanks!

Pulse laser preliminary recognition 
  Hi everyone, I would like to ask if there is a way to recognize your laser has output pulse? I mean, how to distinguish with your eyes or low cost equipment that your laser emit pulse, not CW? Because I heard that the laser meter has two kind: power meter and energy meter. We must know exactly the output regime to use the correct meter, right? If using... more »

Terabeam InGaAs APD receivers on eBay 
  I just bought 31 pieces of an InGaAs APD photoreceiver part, made by Perkin Elmer for Terabeam (a dotcom sort-of-survivor that was going to transmit data via 1550 lasers through skyscraper windows). They have SF11 hemispherical lenses on them, but I haven't taken one apart to see what's inside exactly. They came with the test data.... more »
