Abstract
The reflectivity of a laser due to stimulated Raman scattering (SRS) f rom long scale-length hohlraum plasmas is shown to depend on the dampi ng of ion-acoustic waves. This dependence is observed in plasmas with either low or high ionization states. Since the SRS process itself is unrelated to acoustic waves, these data are evidence of a nonlinear co upling of SRS to other parametric processes involving daughter acousti c waves.
