Research on Stimulated Raman Scattering Spectrum for Cavity Targets at the Shenguang-Ⅱ Laser Facility

摘要

The stimulated Raman scattering (SRS) experiments with half-cavity targets have been carried out at the Shenguang-Ⅱ laser facility. The imitative optic multiple-channel analyser (OMA) spectrograph is used to obtain the SRS experimental spectrum. We have developed a two-dimensional laser plasma interaction (LPI2D)code. The SRS spectrum for half-cavity targets is analysed theoretically and simulated numerically using the LPI2D code. These simulations quantitatively reproduce the experimental results firstly.
