Ion-trapping saturation of the Brillouin instability

Journal Article · · Phys. Rev. Lett.; (United States)
The ion acoustic wave and harmonics driven by stimulated Brillouin scattering are probed by space- and time-resolved ruby-laser Thomson scattering. Corresponding to the 6% backscatter observed, the ion wave is seen to saturate at (5--10)% amplitude, a level quantitatively predictable from the nonlinear frequency shift caused by ion trapping.
