Title: Observation of polarization dependent Raman scattering in a large scale plasma illuminated with multiple laser beams

Abstract

Here, experiments in plasmas produced with 2mm diameter gas filled targets preheated with 10kJ of laser energy have shown that the stimulated Raman scattering (SRS) of a high intensity, 351nm, beam is affected by the presence of a second, counterpropagating, high intensity beam and that has its polarization aligned to the first when the plasma conditions are relevant to ignition by indirect drive. Separate experiments with the crossing beam's polarization rotated to be normal to the first beam's polarization show little change in the SRS backscatter when the second beam is added, consistent with the reduction in the SRS being caused by low frequency waves driven by the ponderomotive force produced by the beating of the two beams.
