The kinetic enhancement of stimulated Raman scattering (SRS) is studied by many authors [4]-[7] in both homogenous and inhomogeneous plasmas. However, the transverse motion is treated using the fluid model in the Vlasov simulation, which thus eliminates the interaction between Weibel instability and stimulated Raman scattering [8]. Another important issue is how the spatial temperature gradient induced by the field ionization affects the evolution of SRS. A 1D1V and 1D2V electromagnetic Vlasov solver is developed for studying the laser-induced SRS.
In this talk, we will introduce the numerical scheme used in our code and the numerical results will be demonstrated in the paper.
