STIMULATED BRILLOUIN SIDESCATTERING IN LASER-IRRADIATED PLASMAS
激光辐照等离子体中的受激布里渊侧向散射

The stimulated Brillouin scattering process under the interaction of high intensity sub-ns pulse laser with plasmas has been investigated, with a larger extent of underde-nse plasma being produced in advance. The occurence of instability of both stimulated Brillouin backscattering and sidescattering can be confirmed simultaneously through careful measurements of the energy and spectrum of the backscattered light, as well as the angular distribution of the sidescattered light, especially its space anisotropy.
