Resumo
A quasi-steady-state approximation for the problem of stimulated Mandelstam–Brillouin scattering (SMBS) in the air as in a multimode acoustic medium is formulated. In this approximation, a numerical solution of the equation for the envelope of the complex light field amplitude is implemented. Based on a series of performed numerical experiments, it is established that the SMBS effect can lead to a discernible increase in the angular divergence of laser beams during the propagation of a sufficiently powerful laser radiation with a wavelength λ = 1.315 μm in air.
