Abstract
Many different nonlinear phenomena and techniques have been used to produce phase conjugate beams. A few years ago, four-wave mixing was proposed as a means of generating a phase conjugate replica of an optical wave.1 Since then, there has been an ongoing search for materials in which to perform four-wave mixing, especially for materials that will respond to extremely weak optical beams.2 Photorefractive materials are some of the most sensitive materials to date for performing optical phase conjugation with the use of only milliwatt power. We report experimental research on the generation of optical phase conjugation in photorefractive materials, undoped and doped KNSBN crystals. Compared with BaTiO3
