Stimulated Brillouin Backscattering Losses in Weakly Inhomogeneous Laser-Produced Plasmas

摘要

Studies of the reflection from a plane solid target plasma produced with a 1TW iodine laser (lambda = 1.3 mu m) at pulse durations of 300 ps are presented. The specularly reflected and the backscattered light was observed separately at different angles of incidence, intensities and spot sizes (up to 400 mu m). Stimulated Brillouin scattering was identified as the main mechanism for backscattering with saturation at 20 - 30% reflection. (Atomindex citation 10:471635)
