To the theory of stimulated brillouine scattering in the field of 2D localized inhomogeneous pumping wave at an arbitrary scattering angle

Abstract

The problem of stimulated Mandelstam-Brillouin scattering (SMBS) in a plasma in the field of a two-dimensionally localized and inhomogeneous pump wave is considered for arbitrary values ??of the scattering angle. Exact solutions of the system of truncated equations for the amplitude of an electromagnetic scattered wave and the amplitude of a sound wave are obtained in the approximation of strong dissipation of sound waves for an arbitrary direction of propagation of the scattered wave. The angular dependence of the intensity of the scattered radiation and its dependence on the inhomogeneity parameter of the pump wave are studied. Keywords: stimulated Raman scattering: SRS, SBS, SBS, SRS, ionic sound, strong dissipation approach.
