Enhancement of Stimulated Brillouin Scattering due to Reflection of Light from Plasma Critical Surface

Abstract
We consider the effect of light reflected from the plasma critical surface on stimulated Brillouin scattering. For an expanding plasma, there will be a certain Mach number where the reflected light acts as a noise source for stimulated—Brillouin-scattering exponentiation. We show calculations and plasma simulations that exhibit significantly enhanced levels of scattering.
