Experiments are under way at the NOVA laser to characterize the saturation of stimulated Raman scattering (SRS) by secondary decays. Recent experiments have shown that SRS is limited by saturation of the SRS Langmuir wave, and that saturation amplitude depends on ion acoustic wave parameters. Decay of the Langmuir wave into an ion wave and either a Langmuir or an electromagnetic wave is a likely candidate to explain this behavior. We will measure the product ion and Langmuir waves from the decay of SRS pumped by 351 and 527 nm beams using Thomson scattering of NOVA's 263 nm probe to resolve the waves' barκ and ω. Each of the products has a barκ and ω distinct from other waves, allowing identification of the instability(s) important to the saturation of SRS. Understanding these decay processes will help to provide a physical basis for the understanding of SRS scaling, and will improve confidence in the design of ignition experiments. The experimental program and results to date will be presented.
