High-resolution double self-pumped phase conjugations with plus c-face incident configuration in a BaTiO3 crystal

Abstract

The geometry of creating two stable self-pumped phase-conjugate outputs in one photorefractive BaTiO3 crystal is demonstrated. This novel geometry provides two phase-conjugate images with a resolution as high as 4 mum (or 114 1p/mm). The reflectivity versus the angle of the incident beam is also investigated.
