摘要

使用平面内（PP）和平面外（SP）激光器组合进行的二维粒子池内模拟研究了直接驱动惯性约束聚变点火条件下的激光等离子体不稳定性。研究结果表明，受激拉曼侧向散射会导致显著的泵浦耗竭，并在拉曼散射光光谱中形成一个缺口，这在实验中已经观察到。

Pump depletion and the Raman gap in ignition-scale plasmas.

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.
