Stimulated Raman Scattering from High Temperature Small-scale Halfraums Plasmas
Abstract
Stimulated Raman Scattering (SRS) has been studied experimentally in high temperature plasmas. The study was performed using the Omega laser at the Laboratory for Laser Energetics (LLE) in Rochester. Approximately 10 TW of power is incident upon targets, distributed among three cones. The hot-halfraums fill with plasma so quickly that, late in time, most of the laser energy is deposited outside the laser entrance hole (LEH), where most of the SRS interaction takes place. The spectrum of SRS light extends way beyond w/2, due to the Bohm-Gross temperature shift. Comparison with predicted spectrum of SRS will be presented.
