Stimulated Brillouin scattering of an electromagnetic wave is investigated analytically in a dissipative magnetized plasma in the presence of negative ions. With an increase in the number of negative ions (maintaining quasi-neutrality), it is found that the growth rate of ion-acoustic waves decreases very slowly up to 50% concentration (i.e. half of the total ionic contribution) of negative ions. Further increase in the number density of negative ions beyond 50% results in a sharp fall in growth rate.

Abstract Stimulated Raman scattering can occur near the quarter critical density in direct-drive fusions, and the frequency of Raman scattered light is about half of the incident light frequency. The second harmonic of the Raman scattered light can be produced due to the inhomogeneity density profile. It can serve as the seed of stimulated Brillouin scattering (SBS). When the second harmonic of stimulated Raman scattering light propagates against the incident light, some components will match to the frequency of backward SBS and SBS is induced. Thus SBS could be enhanced greatly.
