Magnetized laser–plasma interactions in high-energy-density systems: Parallel propagation

We investigate parametric processes in magnetized plasmas, driven by a large-amplitude pump light wave. Our focus is on laser–plasma interactions relevant to high-energy-density (HED) systems, such as the National Ignition Facility and Sandia MagLIF concept. present self-contained derivation of “parametric” dispersion relation for three-wave interactions, meaning wave included equilibrium, similar unmagnetized work Drake et al., Phys. Fluids 17, 778 (1974). For this, we use multi-species plasma fluid model Maxwell's equations. The application an external B field causes right- left-polarized waves propagate with differing phase velocities. This leads Faraday rotation polarization, which can be significant HED conditions. Phase-matching linear relations show that Raman Brillouin scattering have modified spectra due background field, though this effect usually small systems current practical interest. study process call stimulated whistler scattering, where decays electromagnetic ([Formula: see text]) Langmuir only occurs presence required exist.
