On numerical modeling of nonlinear theory equations for stimulated Mandelshtam - Brillouin scattering in plasma
The problem of Mandelshtam - Brillouin stimulated scattering in a homogeneous and inhomogeneous plasma is considered in the approximation of strong dissipation of sound waves, taking into account the nonlinearity of the second harmonic and depletion of the pump wave. It is shown that the simultaneous consideration of two nonlinearity in a homogeneous plasma will lead to a decrease in the reflection coefficient. In an inhomogeneous plasma, taking into account the nonlinearity of perturbations of sound waves, even taking into account the depletion of the pump wave, leads to an increase in the scattered radiation and, consequently, to an increase in the reflection coefficient.
