Photoinduced changes in refractive index in a quadratic electrooptic PLZT ceramic were observed. Thick‐phase holograms were recorded with high diffraction efficiency (η∼ 0.10 to 0.50). The dependencies of the diffraction efficiency on the density of light energy and applied field were determined. The observed amplification effect is explained in terms of photoinduced electrical field components and the quadratic electrooptic properties of the ceramic.
