直接证据表明，在惯性约束聚变（ICF）感兴趣的条件下，与受激布里渊散射（SBS）相关的离子声波（IAW）和与受激拉曼散射（SRS）相关的电子等离子体波（EPW）之间存在时间和空间相互作用。这两种类型的波在等离子体前部的有限区域内生长，但时间不同。在激光脉冲的早期部分已经观察到 IAW 对 EPW 的抑制，并且这种抑制可以通过增加 IAW 的水平来加强。
Direct evidence is presented of the temporal and spatial interplay between ion acoustic waves (IAWs) associated with stimulated Brillouin scattering (SBS) and electron plasma waves (EPWs) associated with stimulated Raman scattering (SRS) in conditions of interest to inertial confinement fusion (ICF). The two types of waves grow over a limited region in the front part of the plasma, but at different times. Inhibition of the EPWs by the IAWs has been observed in the early part of the laser pulse, and this inhibition can be strengthened by increasing the level of the IAWs.
