Abstract
The dependence of the magnitude of stimulated Raman scattering (SRS) o n ion-wave damping has been demonstrated in a high-Z plasma. The ion-w ave damping is varied in a well characterized Xe plasma by varying the concentration of a C5H12 impurity. The reflectivity of SRS is observe d to increase with the concentration of the dopant, demonstrating the effect of ion-wave damping on SRS. The measurements are consistent wit h models in which the amplitude of the SRS-driven Langmuir waves are l imited by a secondary decay into ion-acoustic waves.
