Particle simulations and the analytical solution of coupled mode equations are used to demonstrate that the mode coupling of a primary ion acoustic wave produced by stimulated Brillouin backscatter with a secondary finite-amplitude ion wave propagating at a finite relative angle can reduce the amplitude of the primary ion wave and the backscatter. The simulations and analysis give results that are in qualitative agreement with experimental observations [Baldis et al., Phys. Rev. Lett. 77, 2957 (1996)] of the partial suppression of stimulated Brillouin backscattering (SBBS) when there are simultaneous, overlapping SBBS processes at a finite relative angle, which may influence SBBS reflectivities in other current and future laser-fusion experiments with multiple overlapping beams. © 1998 American Institute of Physics.
