NEAR INFRARED NONLINEAR OPTICAL PHASE CONJUGATION IN PHOTOREFRACTIVE CRYSTALS AND SEMICONDUCTOR MATERIALS PART II: MATERIALS AND APPLICATIONS

Abstract

Materials used in experiments for optical wavefront reversing as a tool for phase aberration correction are reviewed. The recent experimental results in optical phase conjugation in the near infrared are summarized. Photorefractive oxides and their feasibility to use these materials in this wavelength range as well as bulk semiconductors with the corresponding bandgap and dopant are reviewed by listing the nonlinear optical properties and the measured results in optical phase conjugating experiments. Advantages of each material is confronted with the drawbacks. Different enhancement techniques are presented in order to improve the corresponding material parameters. Several applications and experiments are discussed.
