LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR big difference-frequency technology in OPGaAsA method-locked tunable dye laser has actually been created and that is synchronously pumped at superior repetition prices via the doubled output of a mode-locked Nd:YAG laser. The dye laser delivers extreme pulses of 35 psec period w
