摘要：

Self-pumped phase-conjugated (SSPC) images produced by two SPPC beams generated from a single nanosecond-pulsed laser beam are successfully obtained at beam power ratios of up to 4:1. The two SPPC beams are incident on opposite faces [((1) over bar 00) and (100)] of a photorefractive barium titanate (BaTiO(3)) crystal, and the SPPC images are reproduced on the respective crystal faces with high qulaity due to the reduced inteference between the two SPPC beams owing to the delay between the nanosecond pulses of each beam. The quality of the images and the maximum power ratio at which both images are observable are superior to the continuous-wave configuration.
