Experimental Investigations on X-ray Lasers
-
摘要: 自1987年开展X光激光实验以来,在许多物理机制研究上取得重要进展,尤其利用电子碰撞激发机制实现了一系列类氖锗离子的X光激光增益.在驱动能量~600J、脉宽~1.2ns条件下,首先获得19.6~28.6nm间的5条跃迁增益线,GL值约8,利用平面X光反射镜又实现双程放大.时间分辨的强度提高10倍.在此基础上.又完成低能量驱动和预-主脉冲驱动的X光激光增益实验,为在较低驱动能量下实现高增益和准单线的X光激光输出探索有效的技术途径. This paper introduces the progress on X-ray laser investigations in CAEP,including the experiments of X-ray lasers gain of Ne-like Ge pumped by electron-collision excitation, double-pass amplification of X-ray laser, low enery double-pulse driving and X-raylasers pumped by other schemes. The attentions are paid to the experimental principles, designs and results. Some suggestions of future investigations are also discussed.Abstract: This paper introduces the progress on X-ray laser investigations in CAEP,including the experiments of X-ray lasers gain of Ne-like Ge pumped by electron-collision excitation, double-pass amplification of X-ray laser, low enery double-pulse driving and X-raylasers pumped by other schemes.
