中文摘要：
通过对不同激光条件产生的等离子体进行Thomson散射实验诊断，发现在距靶面为150μm的临界密度面内，离子声波双峰强度出现明显的不对称性，而且强峰的位置发生了转移：当等离子体的电子温度较高时，强峰出现在短波方向；当等离子体电子温度较低时，强峰出现在长波方向．光的拉曼散射效应对应地解释了离子声波的双峰结构、双峰强度不对称性及强峰出现的位置．建立了光的拉曼散射与电子的Thomson散射的对应关系．
英文摘要：
With the effective Thomson scattering diagnostic of the laser plasmas produced under different laser conditions, the distinct asymmetry of the two peaks of the ion-acoustic waves are measured 150 μm in front of the target surface. The more intense peak appears at shorter wavelength when the electron temperature is higher, and switches to longer wavelength when the electron temperature is lower. The two-peak strcture, the asymmetry and the position of the more intensity peak of the ion-acoustic waves can be well interpreted with the Raman scattering effect. This paper, for the first time, establishes the corresponding relationship between Raman scattering of light and Thomson scattering of electons in laser plasmas.
