Abstract

Nonlinear interactions of counter propagating waves take place in various nonlinear optical processes attracting attentions of investigators for many years. This is due to problems having a practical importance (for example, wave front conjugation). However, a number of factors that influence on processes quality were exposed by investigators. There is an instability appearance in the system of counter propagating waves among them. An analytical solution for the scheme of two wave have been obtained by now only for strict counter interaction. In the present report some instabilities development is demonstrated by the examples obtained from the mathematical simulation experiments. As an explanation of the some reasons of instability, the question of convective instability (along the interaction region) in the system of counter propagating noncollinear plane waves with unequal amplitudes is studied.
