Abstract

Within the framework of dynamic holography we present a theoretical model based on geometric optics ideas which is capable to describe two wave mixing and four wave mixing processes with waves of arbitrary shape in photorefractive crystals. The model takes into account the nonplanarity of the waves and optical activity of the crystal materials. In the slowly varying amplitude approximation coupled partial differential equations describing the evolution of the wave amplitude are derived. These equations are solved numerically by introducing the lightpaths as characteristics. We study the influence of the beam properties like amplitude profiles and polarization as well as the geometrical arrangements and crystal properties on the two wave mixing efficiency.
