The strong-coupling mode, called the “quasimode”, is excited by stimulated Brillouin scattering (SBS) in high-intensity laser–plasma interactions. Also SBS of the quasimode competes with SBS of the fast mode (or slow mode) in multi-ion species plasmas, thus leading to a low-frequency burst behavior of SBS reflectivity. Competition between the quasimode and the ion-acoustic wave (IAW) is an important saturation mechanism of SBS in high-intensity laser–plasma interactions. These results give a clear explanation of the low-frequency periodic burst behavior of SBS and should be considered as a saturation mechanism of SBS in high-intensity laser–plasma interactions.

Laser plasma experiments reveal rich interplay between laser plasma instabilities. The growth of stimulated Brillouin scattering (SBS) is one of the most significant constraints of laser fusion experiments. In this paper, a mechanism of stabilization of SBS process due to magnetic anisotropy has been presented. Magnetic anisotropy induced by the temporally exponentially growing nonoscillating magnetic moment from inverse Faraday effect (IFE) has been studied.It has been shown that for interaction of Nd laser (λ = 1.06 μm) on solid deuterium target the SBS growth rate (y) ∼ 3.45 ps and the phase velocities of the incident and scattered electromagnetic (EM) waves have been shown to decay exponentially (∼e∼λ1) in this SBS process resulting in wave-number mismatch.
