通过合理而有效地按排多种探测仪器，观察到等离子体Ｘ射线激光介质的空间非均匀现象．在保证入射激光经最佳组合透镜后焦线均匀性前提下，由实验显示等离子体介质的空间不均匀性主要来自靶材质量和调焦精度．此外，入射激光脉宽的大小变化将会引起等离子体整个辐射空间和时间范围的明显变化．
By arranging a variety of detection instruments rationally and effectively, the spatial nonuniformity of the plasma X-ray laser medium is observed. Under the premise of ensuring the homogeneity of the back focus of the incident laser light through the optimal combination of lenses, the experiment shows that the spatial heterogeneity of the plasma medium mainly comes from the quality of the target material and the focusing precision. In addition, the change in the size of the incident laser pulse will cause a significant change in the entire radiation space and time range of the plasma.
