Renaissance of YAG Laser Cavity Construction

-New Construction for Laser Cavity: Introduction of Phase-Conjugate Mirror-

Abstract

Phase-conjugate mirror (PCM) is very important to improve the wavefront distortion due to the optical pumping of solid state laser materials and the inhomogeneity of optical components. In this paper, the reflection experiment of PCM based on stimulated Brillouin scattering and the oscillation characteristics of YAG laser using PCM as a cavity mirror are described.
