摘要
介绍了用于超短超强激光脉冲 -脉冲气体靶相互作用研究的新型差分抽运系统 ,与高效高分辨率大面积透射光栅光谱仪配合 ,进行了超短激光脉冲辐照下氩气喷靶的软 X射线发射特性的实验研究。实验表明 ,该谱仪有足够的灵敏度参与超短强激光脉冲辐照气体靶的软 X射线产生、X射线激光乃至高次谐波实验的软 X射线光谱诊断工作。
A novel differential pump system is presented. Combined with a high efficiency, high spectral resolution large size transmission grating spectrograph, the differential pump system is especially suitable for the research of the ultrashort pulsed laser gas puff target interaction. The experiments on soft X ray spectral diagnosis of Ar puff target irradiated by femtosecond laser pulses are carried out. The results show that the spectrograph is a powerful tool of spectral diagnosis in experiments on the ultrashort pulsed laser gas puff target interaction, optical field ionization soft X ray laser, and high harmonic generation.
