Paper Abstract

In the recent year, the photorefractive effect has become the nonlinear mechanism of choice for highly parallel information processing with low power lasers. The use of these nonlinear interactions has resulted in numerous new applications such as information processing, phase conjugation, image amplifiers and resonators. Under optimized recording conditions, most of the photorefractive crystals now exhibit large gain coefficients in the visible and near infrared wavelengths. Some of these applications based on two wave and four wave mixing interactions in different electro-optic crystals (BaTiO3, KNb03, BSO, BGO, GaAs...) are detailed in the following of this paper. Moreover, the specific properties and the basic mechanisms of the photoinduced index change are also presented.
