Abstract

Abstract

On Shenguang-III prototype facility, eight
$ 3\omega $
(351.0 nm) laser beams are used to produce laser-scale high-temperature plasmas as well as to excite strong stimulated Brillouin scattering (SBS). An additional
$ 4\omega $
(263.3 nm) laser beam, together with a large-aperture Thomson scattering diagnostic system, is applied to obtain the super-thermal collective Thomson scattering (STS) spectra of the ion acoustic waves driven by the SBS process of a
$ 3\omega $
laser beam. By comparing and analyzing the STS spectra and the backward SBS spectra, the temporal and spatial evolution of SBS is revealed.
- Thomson scattering,
- super-thermal,
- stimulated Brillouin scattering,
- inertial confinement fusion
