Description
Growth and saturation of the stimulated Brillouin scattering (SBS) instability has been studied in C, CH, and CH2 laser-produced plasmas which have nearly identical density profiles. The backscattered reflectivity is highest for the CH2 plasma (∼15%) and up to ∼5 times lower for the pure carbon plasma. This result is explained by the stationary inhomogeneous theory of SBS and confirmed by numerical simulations provided one allows for the nonuniform expansion of hydrogen and carbon ions that leads to an axial asymmetry of the SBS gain and results in the observation of a blueshifted scattered light spectrum from CH targets. copyright 1996 The American Physical Society
