Stimulated Raman scattering in the presence of stimulated Brillouin scattering
Journal Article
·
· Phys. Fluids; (United States)
Particle simulations of stimulated Raman scattering (SRS) are presented in which stimulated Brillouin scattering (SBS) also occurs. Frequency spectra of forward and backscattered light are compared for various ratios of ion mass to electron mass. SBS is seen to weaken the SRS backscattering in all cases in which the plasma density profile includes the quarter-critical density. For cases in which the plasma density remains below quarter-critical, the SRS backscattering is not strongly affected by the SBS. In long-scale length, quarter-critical density cases for which m/sub i//m/sub e/ = 400, large amplitude density perturbations grow and persist.
