| 摘 要： | 利用(国内最近研制成功的)带聚酰亚胺膜底衬的金透射光栅与软X射线条纹相机相配合,(在LF11~#激光装置上)使用波长为0.53μm的激光打靶,测量了平面Au靶软X射线时间分辨能谱。测量结果观察到了金等离子体的O带辐射强度随时间增加的现象。文章计算了光栅的衍射效率,并讨论了影响测量谱的几个关键因素。

| Abstract: | Time-resolved soft X-ray spectra measurement has been deveoped for studying laser-produced plasmas by using a gold transmission grating (TG) coupled to a soft X-ray streak camera. Recently we fabricated the TG with a line density of about 8531/mm on a substrate of a 0.5 micron thick polyimide membrane. Timeresolved spectra of gold (20μm in thickness) planar targets were abtained. The planar targets were irradiated with 680 ps laser pulses (λ=0.53μm) from the LF11# Nd: glass laser system. The emission intensity with temporal variation for O band from gold plasmas was observed. |
