NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~one µm with intracavity mid-IR change-frequency generation in OPGaAsA manner-locked tunable dye laser is produced which can be synchronously pumped at substantial repetition rates by the doubled output of the manner-locked Nd:YAG laser. The dye laser supplies rigorous pulses of 35 psec period which can be g
