Stimulated forward Raman scattering in density rippled magnetized plasma

Abstract

In inertial confinement fusion, the development of stimulated Raman scattering is observed in the presence of an azimuthal magnetic field and a density rippled plasma. The Gaussian laser beam propagating through a density rippled plasma is amplified by forward Raman scattering in the presence of an azimuthal magnetic field, resulting in two radially localised electromagnetic sideband waves and a lower hybrid wave. It is observed that as the laser power is increased, the growth rate in the presence of density rippled plasma reduces the probability of plasma pre-heating in ICF.
