Abstract
We have measured the characteristics of saturated ion-acoustic waves in ine rtial confinement fusion plasmas. A 263-nm probe laser has been applied to simultaneous Thomson scatter on both ion-acoustic waves excited by thermal electrostatic fluctuations and by stimulated Brillouin scattering of a kilo joule laser beam of varying intensity. The Thomson scattering spectra show saturated ion-wave amplitudes for intensities above 5 x 10(14) W cm(-2) con sistent with three dimensional nonlinear wave modeling.
