摘要:

采用Vlasov-Maxwell方法模拟了受激布里渊散射级联中的反斯托克斯散射和斯托克斯散射。在高强度激光与等离子体相互作用中,在第二阶段SBS再散射之后,将发生受激反斯托克斯布里渊散射(SABS)。提出了SABS的机理来解释这一现象。并且SABS将与SBS再散射竞争以确定SBS的总反射率。因此,包括SABS在内的SBS再散射是SBS的一种重要饱和机制,在强激光与等离子体相互作用中应予以考虑。

英文摘要:

The anti-Stokes scattering and Stokes scattering in stimulated Brillouin scattering (SBS) cascade have been researched by the Vlasov-Maxwell simulation. In the high-intensity laser-plasmas interaction, the stimulated anti-Stokes Brillouin scattering (SABS) will occur after the second stage SBS rescattering. The mechanism of SABS has been put forward to explain this phenomenon. And the SABS will compete with the SBS rescattering to determine the total SBS reflectivity. Thus, the SBS rescattering including the SABS is an important saturation mechanism of SBS, and should be taken into account in the high-intensity laser-plasmas interaction.
