Abstract
Laser-plasma instabilities under ignition conditions for direct-drive
inertial confinement fusion are studied using two-dimensional Particle-in-Cell
simulations with a combination of in-plane (PP) and out-of-the-plane (SP)
lasers. The results show that stimulated Raman side scattering can induce
significant pump depletion and form a gap in the Raman scattered light spectra
that have been observed in experiments.
