Kinetic Simulations of Magnetized Laser-Plasma Interactions: Raman and Whistler Scattering
ORAL
Abstract
We present simulations of magnetized laser-plasama interactions using the one-dimensional kinetic code SAPRISTI [S. Brunner, E. J. Valeo, Phys. Rev. Lett. 93, 145003 (2004)]. This code utilizes finite-difference methods to solve the Vlasov-Maxwell system of equations, including the full non-linear kinetic dynamics of electrons and ions in the longitudinal direction, and a cold-fluid model of transverse dynamics. The code has been updated to include an external magnetic field in the longitudinal direction. We model stimulated Raman scattering with a background B field, and discuss ``stimulated whistler scattering'', where a pump light wave decays to a Langmuir wave and an electromagnetic whistler wave. This talk will discuss the algorithm development and results for various simulations.
