使用高分辨平焦场谱仪，在“星光”激光器上，对类氖钛Ｊ＝０—１，３ｐ—３ｓ跃迁３２６ｎｍ软Ｘ射线激光空间发射区域进行了实验测量，并与ＬＡＳＮＥＸ和ＸＲＡＳＥＲ程序模拟结果作了比较．实验采用预脉冲打靶技术，预、主脉冲时间间隔５ｎｓ，峰值能量比为１％．结果表明：当驱动能量在５０—１５０Ｊ范围内变化时，等离子体介质中Ｘ射线激光发射区与驱动能量大小密切相关，并随之增大而增大
High-resolution tele-coherent spectrometer was used to experimentally measure the spatial emission region of 32.6-nm soft X-ray laser with the type of Neodymium titanium J = 0-1, 3p-3s on the “Starlight” laser and compared with LASNEX and XRASER Program simulation results were compared. The experiment uses pre-pulse shooting technology, pre-main pulse time interval of 5ns, the peak energy ratio of 1%. The results show that when the driving energy varies from 50 to 150 J, the emission area of X-ray laser in the plasma medium is closely related to the driving energy and increases with the increase
