摘    要: 报道了“神光 Ⅱ”装置上Au大柱腔靶产生的受激Raman散射光谱。通过分析实验条件和测量结果,排除了散射光谱来自增强非相干Thomson散射的可能性,发现用丝化不稳定性与受激Raman散射的耦合能合理解释观测到的Raman光谱。考虑到丝化不稳定性与SRS的耦合,测量到的散射光谱依然能用于密度诊断,其结果与对流SRS理论的计算值相差不到10%。

关 键 词:受激Raman散射  丝化不稳定性  朗道阻尼  增强非相干Thomson散射

Abstract:Time-resolved and time-integrated stimulated Raman scattering (SRS) spectra from gold hohlraum irradiated with 351nm laser light are measured. The experimental results are inconsistent with the prediction of the convective SRS theory and enhanced incoherent Thomson scattering model. The analyses show that the prediction of SRS in filaments agrees reasonably with the experimental results. Based on the model of the coupling between filaments and SRS, the method of diagnosing plasma density with SRS spectrum was developed. The calculated result shows that the difference between the model and the convective SRS theory is less than 10%, which agrees with the conclusion made by Afshar-rad.
Keywords:Stimulated Raman scattering  Filamentation instability  Landau damping  Enhanced Thomson scattering
