Název v původním jazyce

Stimulated Raman scattering in the presence of trapped particle instability

Popis výsledku v původním jazyce

The behaviour of electron gas in a laser plasma corona is studied in the presence of stimulated Raman scattering (SRS). The 1 D Vlasov-Maxwell model describing plasma relevant to the experiment PALS (Prague Asterix Laser System) is in operation. For thesolution of Vlasov equation for the electron distribution function a Fourier-Hermite transform method is used. For the numerical stabilization a small collision term is added to the Vlasov equation keeping its value realistic for the condition relevant to the PALS experiment. The dominant wave modes ill our model are both the backward (SRS-B) and the forward (SRS-F) Raman scattering, each of them accompanied by the forward going electron plasma wave. Several mechanisms were identified such as the SRS-Bplasma wave spectral broadening due to a trapped particle instability (TPI) or the formation of an electrostatic quasi-mode by non-resonant interaction of SRS-B and SRS-F plasma waves.
