Abstract

We report theoretical and experimental study of two-wave mixing dynamics in the film of azo-containing polymer with liquid crystal properties. The developed model of energy coupling in the polymer considers the effects of light absorption, nonlinear saturation and diffusion. Two geometries of exiting beams incidence were considered: (I) symmetrical incidence with respect to film normal and (II) incidence of differently tilted incoming beams. In the carried out experiments we have investigated the dynamics of two-beam coupling using the prototype of adaptive interferometer. The influence of operation conditions on the response characteristics was studied. The obtained theoretical results are in good agreement with the experimental data.
