Backward Raman amplification of laser pulses in randomly inhomogeneous plasmas
Abstract
Current experiments on backward Raman amplification (BRA) of laser pulses in plasmas deal with strong enough random inhomogeneities in plasma concentrations capable of substantially modifying linear and even nonlinear stages of BRA. We present a simple BRA theory taking into account modifications caused by the random inhomogeneities. We show that the modified linear theory is not inconsistent with recent BRA experiments. We also give quantitative conditions for entering nonlinear BRA regimes, modified by the presence of the inhomogeneities.
