本文简要介绍了各种用途的激光等离子体X射线源的现状。软X射线应用中的主要问题之一是源产生的碎片，这降低了X射线光学的质量。为了克服这个问题，我们建议使用低温靶或高压喷气靶。低温靶提供的X射线强度与激光照射的固体靶的X射线强度一样强。喷气靶是通过喷嘴脉冲注入高密度气体而产生的。本文描述了用脉冲激光照射的喷气靶产生的等离子体的实验。所获得的结果将允许开发一种高效和无去屑的激光产生的X射线源，这将有助于在各个领域的应用。
We briefly describe the present status of laser plasma x-ray sources for various applications. One of the main problems in soft x-ray applications is the production of debris by the source, which degrades the quality of the x-ray optics. To overcome this problem we propose the use of a cryogenic target or a high pressure gas-puff target. The cryogenic target provides x-rays as intense as those from a laser-irradiated solid target. Gas-puff targets are created by the pulsed injection of high-density gas through a nozzle. Experiments with plasmas produced using a gas-puff target irradiated with a Nd: YAG laser are described. The obtained results would allow for the development of an efficient and debrisless laser-produced x-ray source that would be useful for applications in various fields.
