THE BASIC PRINCIPLES OF HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~one µm with intracavity mid-IR change-frequency era in OPGaAsA method-locked tunable dye laser is designed which can be synchronously pumped at high repetition prices because of the doubled output of a manner-locked Nd:YAG laser. The dye laser offers powerful pulses of 35 psec duration which have been widel
