The experiments used the “Xingguang Ⅱ” laser facility to irradiate gold disks at some chosen angle of incidence. In this paper, we report the absorption and angular distribution of scattered lights of 0.351μm laser light by Au disks. The experiments have shown that the absorption by Au disk is higher than that irradiated with 0.53 or 1.05μm laser light. The angular distribution of scattered lights proves that scattered lights include stimulated Brillouin scattering and specular reflection from critical surface. Based on inverse bremsstrahlung absorption, the absorption obtained by simulation agrees with the experimental results.
