摘要

研究了多种等离子体中受激布里渊散射(SBS)的散射辐射谱线宽问题。结果表明，SBS的阈值和光谱组成可以通过改变等离子体中物质的浓度而改变。揭示了存在频率线宽与离子声频率相当的散射辐射谱的可能性。

Spectrum linewidth of SBS in collisionless plasma with two species of ions

A problem of scatterd radiation spectrum linewidth of stimulated Brillouin scattering (SBS) in multi-species plasma is studied. It is shown that the threshold and spectral composition of SBS can be varied by changing the concentration of species of the plasma. A possibility of existence of the scattered radiation spectrum with the frequency line width comparable to the ion-acoustic frequency is revealed.
