中文摘要：
自软X光激光发现以来，实现低激发阈、台式软X光激光一直是一个十分重要的研究方向。利用毛细管放电激励产生软X光激光，是实现台式软X光激光的主要方案之一。实验采用20cm长的毛细管，利用X射线二极管（XRD）探测了毛细管放电抽运软X光46．9nm激光输出。研究表明，放电电极的材料并不是影响激光输出质量的决定性因素。但考虑到电极元素的飞溅，在长时间的实验研究中，选择钼电极更为有利。电极形状在放电过程中只影响预脉冲的导通情况，而对激光影响并不大。在更长毛细管的实验中，选择锥状端面的电极将有利于预脉冲的导通，以便获得激光输出。
英文摘要：
Since the first soft-X-ray was achieved, to realize the low excited threshold and table-top soft-X-ray laser is a significant research. Capillary discharge soft-X-ray laser is one of the crucial quomodo to realize table-top soft-X- ray laser. The capillary discharge 46.9nm soft-X-ray laser has been detected by X-ray diffraction diode（XRD）. The experimental results indicate that the influence of the material of the electrode on capillary discharge soft-X-ray laser is not the critical factor. Considering the sputtering of the element, choosing the electrode made of molybdenum is advantageous. The shape of the electrode mainly influences on the conduction of the pre-current pulse but not on laser, and it is easier for the pre-current pulse to conduct in longer capillary by choosing the pyramidal electrode.
