从1984年x射线激光器的发现开始，激光产生的等离子体存在了近十年，这是唯一可以获得大放大软x射线辐射的介质。本文回顾了最近首次在放电产生的等离子体柱中实现大的软x射线放大，利用快速毛细管放电来碰撞激发Ne - like Ar的46.9 nm跃迁。本文报道了氩离子放电泵浦放大器的参数化、等离子体柱的动力学研究和激光脉冲时程的测量结果。讨论了短波激光操作的发展前景。
Starting with the discovery of x‐ray lasers in 1984, laser‐created plasmas remained for almost a decade, the only medium in which large amplification of soft‐x‐ray radiation could be obtained. In this paper the recent first demonstration of large soft‐x‐ray amplification in a discharge‐created plasma column, realized utilizing a fast capillary discharge to collisionally excite the 46.9 nm transition of Ne‐like, Ar is reviewed. Results of the parametrization of the Ar IX discharge‐pumped amplifier, the study of the dynamics of its plasma column, and the measurement of the time history of the laser pulse are reported. Prospects for laser operation at shorter wavelengths are also discussed.
