Euler-Vlasov approach applied to the wave transformation in laser plasma

Abstract

The non-linear stage of stimulated Raman back-scattering is examined numerically in a collisionless non-relativistic laser plasma. The Euler-Vlasov method is applied in the simplest case of linearly polarized incident electromagnetic wave in 1-D geometry. The method of solution is a Fourier-Hermite expansion of the electron distribution function. The resulting ordinary differential equations are solved for the case corresponding to the interaction of the PALS laser beam with the plasma corona. The time evolution of the electron distribution function is visualized.
