Abstract

Backward stimulated Raman scattering using one-dimensional relativistic Vlasov code is investigated. For conditions similar to those of Single-Hot-Spot experiments, the growth and saturation of SRS are studied. Analysis of electron distribution function, longitudinal electrostatic fields, transverse electromagnetic fields, and electron density shows that kinetic effects play an important role in the saturation of this instability. SRS amplifies the longitudinal field amplitude and could trap, accelerate, and preheat the electrons.
