Paper Abstract

Self-diffraction in the semilinear generator geometry is investigated using statistical approach. A dynamical hologram is formed in the process of the four wave mixing of the signal image which undergoes self-diffraction and the reference image with their fannings on the background of the previous expositions with different signal images and reference beams. Result of this approach is a system of the coupled waves equations for the time evolution of the amplitudes of the conjugated waves, noise, signal waves and the correlations of the refraction index variations and phase distributions of the waves. Comparison of the numerical modeling results and physical experiments in the geometries of double phase conjugate mirror and semilinear generator with BTO and BOS crystals shows good qualitative concordance.
