Paper Abstract

Effects of spatiotemporal transformation of grating shape at nonlinear holographic recording in absorbent photopolymer have been investigated. We present an analytical model of dynamics of (N+1) spatial harmonics of spatial grating profiles with taking into consideration both record mechanisms (polymerization and components diffusion), absorption, interference pattern contrast and optional photopolymerization nonlinearity. Also we take into consideration so called additional gratings (AG) formed as a result of two waves mixing. On the base of numerical simulation we examined an influence of the material and record parameters on 2D spatial profiles of gratings.
