The Amplification of an Amplitude Modulated Signal Beam Via Two-Wave Mixing in Photorefractive Media

Abstract

Two-wave mixing in photorefractive media has been studied theoretically and experimentally by a number of researchers, and a wide range of prospective applications of the effect have been demonstrated or proposed. Recently, Hamel de Montchenault et al., have demonstrated the amplification of high frequency amplitude modulated signals via two-wave mixing in BSO.1,2 In this paper we develop a theoretical framework for the analysis of two-wave mixing with an amplitude modulated signal beam. Preliminary experimental confirmation of the theory is provided.
