The experiment was performed at the Asterix IV iodine laser with a prepulse 5 ns before the main pulse. Under optimum focusing conditions for main pulse and prepulse the X-ray laser beam splits into two beamlets along the target surface at its output end of the 2.5 cm long plasma column. The splitting was still observed when the prepulse alone was defocused.

实验发现在抽运激光主、预脉冲最佳聚焦条件下， X射线激光束在2.5 cm长的线状等离子体输出端沿靶面方向分裂成两束；在抽运预脉冲单独散焦条件下，仍然观察到这一分裂现象；但是当抽运主、预脉冲同时散焦时，这一分裂现象逐渐消失并获得了半宽度只有40 μm的非常窄的近场像。

The suitability of the different processes was analyzed by observing the weld appearance,studying the microstructure and measuring the mechanical properties of the joint.The results show that a favorable weld can be obtained under the suitable parameters by laser beam welding or tungsten inert gas welding with filler metal.The TIG welded joint has a wider HAZ,and the laser welde...

试验结果表明：在工艺参数合适的条件下，加焊丝TIG焊和激光焊均能获得成形较好的焊接接头；TIG焊接头热影响区较宽，焊缝深宽比小，而激光焊时热影响区不明显，焊缝深宽比大；两种焊接方法所获得的焊缝区组织均为均匀的等轴晶，但激光焊时焊缝组织更细，从而使接头抗拉强度大幅度提高，达到母材的94%左右。
