Query: SRS-SBS competition and nonlinear laser energy absorption in a high
  temperature plasma   Stimulated Raman and Brillouin scattering of laser radiation in a plasma
corona are outstanding issues for the inertial confinement fusion. Stimulated
Raman scattering may produce absorption of a significant fraction of laser
energy near the plasma quarter critical density associated with plasma
cavitation and generation of hot electrons. By contrast, stimulated Brillouin
scattering operates in a lower density plasma and prevents the laser light
access to the absorption region. In the present paper, we report the results of
analysis of competition of these two parametric instabilities with a series of
one-dimensional kinetic simulations of laser-plasma interactions. By
controlling the Brillouin backscattering through variation such plasma
parameters as ion acoustic wave damping, divergence of the plasma expansion
velocity or the laser bandwidth, we demonstrate the possibility of controlling
the level of nonlinear laser absorption and scattering in a hot, weakly
collisional plasma.
