Photorefractive crystals are materials whose index of refraction is altered under illumination by light. These crystals are both photoconductive and electrooptic. When a nonuniform light intensity pattern is present in the material, photocarriers are generated and redistributed, creating space charge electrical fields which change the refractive index locally. These crystals are ideal media for real-time holography, and applications include wave amplification, image processing, phase conjugation, and laser beam steering for optical interconnects.
