Abstract

Plasma waves driven to large amplitude by the Raman backscatter instability (SRS) have been observed directly, using frequency- and wavenumber-resolved ruby Thomson scattering. Measurements of their relative amplitudes agree with predictions of nonlinear warm plasma wave steeping theory up to the maximum observed amplitude os the fundamental component. The Thomson scatter spectra was also frequency-, wavenumber-, and amplitude-resolved. Both of the decay products of SRS, the daughter light wave and the plasma wave fundamental, were detected simultaneously and found to be correlated in both frequency and amplitude.
