Abstract

The results of theoretical and experimental studies of the photorefractive effect in two different classes of materials--perovskite BaTiO₃ and tungsten bronze SBN--have been examined. The interesting features of these measurements indicate that two-beam coupling coefficients, response times, and absorption coefficients enhanced significantly in doped crystals which appear to be suitable for future device concepts. A comparison of these materials showed that Ce-doped SBN:60 single crystals are superior to BaTiO₃ for use in photorefractive applications due to higher two-beam coupling, sensitivity, and overall flexibility of tungsten bronze crystals.
