激光等离子体中相干Thomson散射的实验研究

Collective Thomson Scattering from a Laser-Produced Plasma

摘要: 在“星光II”装置上进行了相干Thomson散射实验。实验中以0.35μm激光为作用束，以0.53μm激光作为探针光束，散射光采用反射式收光系统配光谱仪、条纹相机和CCD记录，得到较高时间和空间分辨散射光谱，分析得出时间变化的激光等离子体参数和ui。

Abstract: Time-resolved Thomson scattering was successfully performed to diagnose the parameters of laser-produced gold plasma.The time dependence of and ion drift velocity ui was also obtained to benchmark hydrodynamic simulations.
