Abstract

This article contains the theoretical description of waves' propagation in an isotropic noncentrosymmetric slightly nonlinear and slightly absorbing medium with weak spatial dispersion in noncolinear interaction scheme. The calculations were carried out by expansion on normal waves. The self-action of a powerful wave and its influence on the weak wave were taken into account. The equations describing the double frequency generation process at nonlinear wave interaction were derived by the slowly varying amplitudes method. These equations were analyzed up to first-order infinitesimal precision. The powerful wave and the weak one generate the complicated interference field, so that the amplitude of a double frequency wave has the complex spatial distribution by transverse coordinates, which depends on the wave's and frequency's disparities. The angular spectrum of the double frequency wave has been analyzed.
