Paper Abstract

In this paper we present enhanced four wave mixing with a sinusoidal phase shift introduced in the forward propagation pump beam. The intensity distribution on the crystal is consequently modulated by a sum of frequencies each scaled and phased according to an ordinary Bessel function. The frequency analysis of the photorefractive band transport model shows that the imposed sinusoidal phase shift provides information on both phase and amplitude of the space charge field.
