Abstract
The photorefractive effect was observed in a sample of BaTiO, crystal. In two-beam coupling experiments, the crystal failed to amplify the signal beam even though experimental configurations that provided other researchers with large gains were used. However, beam fanning, a two-beam coupling effect, was observed. The unmeasurable gain of our crystal in twc-beam coupling experiments might be due to multiple domains in the crystal or competition between hole and electron charge carriers. In addition, a self-pumped phase conjugate mirror was made using the "cat" configuration. The formation of the phase conjugate mirror in the crystal was observed using the image distortion correction capability of a phase conjugate beam.
