Paper Abstract

Large signal two-wave mixing in photorefractive materials was studied. A theory based on the Kukhtarev-Vinetskii's model was developed. The coupled-mode equations for large modulation was obtained and their numerical solutions were found. It is shown that large modulation reduces the coupling coefficient of the two-wave mixing interaction, and, therefore, the effective gain. Theoretical results of large modulation agree well with experimental measurements.
