New study and application of phase conjugation with photorefractive crystals

Abstract

A theoretical and experimental study of four-wave mixing in photorefractive crystals like SBN and BaTiO₃ will be presented. A detailed theoretical analysis of the beam coupling as well as new experiments and applications will be described through a distortion ; among them, oneway optical field imaging, a passive (no external pumps) phase conjugate mirror which is pumped by the signal and its use in a laser resonator.
