摘要：

Stimulated Brillouin scattering (SBS) is investigated one dimensionally under conditions when the typical growth rate is comparable with the ion acoustic frequency. The equations for the three-wave interaction are modified according to strong coupling. Studies of SBS in homogeneous plasma slabs exhibit the onset of steady-state solutions. A reflecting rear boundary can cause the backscattering to show nonstationary behavior. In addition, inhomogeneous plasma profiles that include the critical density are studied using the electromagnetic wave equation together with a hydrodynamic approach for the ion fluid.
