摘要

We have used gas-filled targets irradiated by the Nova laser to simulate National Ignition Facility (NIF)rnhohlraum plasmas and to study the dependence of Stimulated Raman (SRS) and Brillouin (SBS) Scattering onrnbeam smoothing at a range of laser intensities (3ω, 2 - 4 10~(15)Wcm~(-2)) and plasma conditions. We haverndemonstrated the effectiveness of polarization smoothing as a potential upgrade to the NIF. Experiments withrnhigher intensities and higher densities characteristic of 350eV hohlraum designs indicate that with appropriaternbeam smoothing the backscatter from such hohlraums may be tolerable.
