Abstract

We propose a novel mutually pumped phase conjugator with +c-face incident geometry in a photorefractive pentagon-shaped 0o-cut BaTiO3 crystal. By selecting the appropriate geometry, such as the orientation between two mutual incoherent beams and the special cut crystal's c-axis a novel configuration can be formed in the crystal when the mutually pumped phase conjugation established. This configuration provides more efficient interaction, which offer with fast response and high stability of phase-conjugated signal, and even high-resolution image restoration.
