The experiments on gold-disk and hohlraum targets irradiated by laser beams with wavelength of 0.35 μm (Xingguang-II) and 0.53 μm (Shenguang-I) are performed. The characteristics of hot electrons and the SRS (stimulated Raman light scattering) produced by shorter wavelength laser are experimentally studied. Associated with the measurement of backward SRS, the production mechanism of hot electrons is preliminarily analyzed in laser plasma with shorter wavelength.
