High-power laser interaction with plasma and its amplification by stimulated Raman backscattering model

Abstract

In this paper we have investigated three wave interaction analytically for stimulated Raman back-scattering in resonance and non-resonance conditions in an under dense plasma. We have solved equations by similarity transformations and have found self similar solutions. It has been shown that by increasing time, maximum of amplified pulse increase constantly while the duration decrease inversely. Effects of initial seed pulse's amplitude and detuning parameter have been investigated.
