YAG:Nd Scanning Laser System with Phase Conjugation and Master-Oscillator with PLZT-Based Intracavity Spatial-Time Light Modulator

Abstract

The feasibility of accurate control over direction of high power beam of a laser amplifier with a help of a signal generated by a low-power master-oscillator with an intracavity light-controlled spatial-time light modulator (STLM) of the PROM type was demonstrated in paper [1]. The PROM type modulator has a low optical strength (~0, 1 J / cm2) in respect to single-pulse radiation and a large period of reversal (~0, 1 s).
