    • An X-ray laser (10), and related methodology, are disclosed wherein an X-ray laser target (12) is illuminated with a first pulse of optical laser radiation (14) of relatively long duration having scarcely enough energy to produce a narrow and linear cool plasma of uniform composition (38). A second, relatively short pulse of optical laser radiation (18) is uniformly swept across the length, from end to end, of the plasma (38), at about the speed of light, to consecutively illuminate continuously succeeding portions of the plasma (38) with optical laser radiation having scarcely enough energy to heat, ionize, and invert them into the continuously succeeding portions of an X-ray gain medium. This inventive double pulse technique results in a saving of more than two orders of magnitude in driving optical laser energy, when compared to the conventional single pulse approach.
    • 公开了一种X射线激光器(10)和相关方法,其中用相对长的持续时间的第一脉冲光学激光辐射(14)照射X射线激光靶(12),其具有几乎不足够的能量以产生狭窄的 和均匀组成的线性冷等离子体(38)。 光束激光辐射的第二个相对较短的脉冲(18)以大约光速从头端到末端均匀地扫过等离子体(38)的长度,以连续地照亮等离子体(38)的连续后续部分 ),其具有几乎不足够的能量以加热,电离和将它们转换成X射线增益介质的连续后续部分的光学激光辐射。 与传统的单脉冲方法相比,本发明的双脉冲技术在驱动光学激光能量方面节省了两个以上的数量级。
