| 摘 要： | 为探索和研究新的X光激光泵浦机制,我们研究了泵浦靶辐射X射线特性。先后在“星光”和“神光”激光装置上开展了该项工作。主要介绍“神光”装置上的实验工作。实验所用泵浦靶材料为Na/F和Cu。实验给出了Na/F和Cu靶辐射X射线谱(波长范围分别为1.1～1.5nm,1.1～1.3nm);给出了X射线相对强度随激光功率密度及靶厚度的变化情况。并比较了靶前、后X射线相对强度。同时,实验还给出了线状泵浦源辐射X射线的空间分布。

| Abstract: | In order to explore new pumping mechanism of x -ray lasers, we have studied the x rays radiated by the pump target. The experiments were successively performed at "Xing guang" and " Shen guang" facilities. The results obtained at " Shen guang" are emphatically introduced in this paper. The targets used are made of Na/F or Cu. The x -ray spectra from Na/ F or Cu (wavelength is respectively within 1.1- l.5nm and 1.1- 1.3nm) are given. The curves of the x -ray relative intensity versus laser intensity and thickness of the target are showed. The x-ray relative intensity in front of the target is compared with that in back of the target. Meanwhile, the spatial distribution of the x rays from the line pumping source is obtained in the experiment. |
