LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR change-frequency technology in OPGaAsA manner-locked tunable dye laser continues to be made which can be synchronously pumped at large repetition fees through the doubled output of the manner-locked Nd:YAG laser. The dye laser delivers powerful pulses of 35 psec length which hav
