Recent Progress of Stimulated-Brillouin-Scattering Phase Conjugation Mirrors for High-Power Laser System

Abstract

A phase conjugation mirror with stimulated Brillouin scattering (SBS-PCM) is useful to compensate for thewavefront distortion due to thermally-induced aberration and depolarization of average power that occurs withsolid state lasers. Use of the SBS-PCM is a promising approach toward power scaling of the solid-state laser. The basic properties of SBS materials are summarized, and several applications are reviewed.
