| 摘 要： | 在星光激光装置上, 使用X射线多层膜反射镜、铝滤片及X射线CCD探测器组成高灵敏度空间分辨探测系统, 对用预脉冲技术产生的类Ne钛单线 (J=0-1, 3p-3s跃迁)软X射线激光输出特性进行了测量。由实验得到了类Ne钛X 射线激光束近场与距靶端32mm处(准远场)强度的空间分布, 给出了该激光束在近场强度最大区域的空间尺度(FWHM)约为72μm×31μm, 以及在垂直靶面与平行靶面方向的束发散角分别约为4mrad与9mrad。

| Abstract: | The output characteristics of a Ne like Ti single X ray laser produced using a ppulse technique are measured at Xingguang laser facility. A highly sensitive and spatial resolved detector consisting of X-ray multilayer mirrors, Al filter and an XUV CCD camera is used in the experiment. The spatial intensity distributions of the Ne like Ti X ray laser in near field and the plane 32mm from the laser output end (quasi far field) have been obtained. The dimension of the strongest intensity region is given to be about 72μm×３１μm. Also, the divergences of the laser beam are gained. The divergence in the direction perpendicular to the target surface is about 4mrad and in the parallel direction about 9mrad. |
