The propagation of two beams of light with slightly different frequencies through a photorefractive media is investigated. In this process, the refractive index experienced by either wave is modified with the intensity of the wave. The coupled nonlinear Schrödinger equation that models the beam propagation is derived from wave equation and solved analytically. The existence of soliton like solutions for the photorefractive media is also verified. © 2011 World Scientific Publishing Company.
