| Abstract: | We study the nonlinear interaction of a system of incident and reflected electromagnetic waves of arbitrary polarization,
propagating in a quasihomogeneous plane layer of isotropic plasma obliquely to the boundary, with scattered electromagnetic
waves. These waves are coupled in the double stimulated Mandelstam-Brillouin scattering by a common sound wave that is parallel
to the layer boundary. We examine the influence of the wave polarization on the threshold intensity, instability growth rate,
and characteristics of the stationary solution. It is found that the nonlinear interaction scales are different for waves
of different polarization. In particular, this leads to a change of the wave polarization in the course of the interaction.
