Paper Abstract

Mutually pumped phase conjugator with +c-face incident geometry is first demonstrated in a photorefractive pentagon-shaped 0 degree(s)-cut BaTiO3 crystal. Designed choosing the geometry such as the orientation between two mutual incoherent beams and the 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, and even high resolution. Two very stable and rather fast phase-conjugate signals with 22% reflectivity can be generated in 0.3 s. Two images with fine structure as high as 8.8 micrometers can be resolved.
