Results are presented of light absorption in a series of wavelength scaling experiments recently completed at LLNL. The Argus facility was used to do target studies at 1.06..mu..m, 0.53..mu..m and 0.35..mu..m. Box calorimeter scattered light measurements implied greatly improved laser light absorption for both high Z and low Z plasmas at laser wavelengths shorter than 1.06..mu..m. Furthermore, at the 0.35..mu..m laser wavelength, the inferred absorption is nearly 100% over a substantial range of incident laser intensities. Our results further show a dramatic decrease in the stimulated Brillouin scattered light at 0.35..mu..m relative to the values at 1.06..mu..m and 0.53..mu..m.
