Optical scatterng measurements from 1. 06. mu. m, and 0. 35. mu. m laser heated targets

Scattered light measurements have been obtained on Argus disk target experiments at 1.06 ..mu..m, 0.53 ..mu..m, and 0.35 ..mu..m laser wavelengths. We present backscatter measurements taken near the three laser wavelengths for SBS, and measurements of the three-halves and second harmonics taken during the two longer wavelength laser irradiations. The SBS measurements show the strong influence of the increased absorption at the shorter laser wavelengths. The spectra of the three-halves harmonic emissions are analyzed to provide a time averaged electron temperature at quarter critical density. Time resolved Raman scattering data are presented for gold and Be disks irradiated with up to 180 J of green light.
