Abstract
Self-aligning phase-conjugate mirror configurations have been extensively investi gated in high-gain photorefractive materials such as BaTiO3 and SBN. While many applications may be envisaged tor such devices, currently available materials are perceived as having response times that are too slow to be compatible with commercial requirements. The response times of photorefractive effects scale as the inverse of the incident intensity, leading to the current interest in increasing the intensity by confining the interacting beams within a waveguide geometry.
