本文讨论了超短脉冲X射线技术的最新进展。基于飞秒激光等离子体的X射线源现在可以产生亚皮秒的软X射线脉冲，光子能量从1010 eV到10106 eV，并且具有入射激光到宽带X射线的高转换效率。高速X射线探测器和软X射线光学的最新进展使得使用这种源作为时间分辨X射线科学的实验工具变得切实可行。其他可能的生成技术，如激光电子束散射，有望进一步扩大这一领域的实验能力。
In this paper, we discuss recent advances in ultrashort-pulse X-ray technology. Femtosecond laser-plasma based X-ray sources can now generate sub-pico-second soft X-ray pulses, with photon energies from ≈ 10 eV to ≈ 106eV, and with a high conversion efficiency of incident laser light to broadband X-rays. Recent advances in high-speed X-ray detectors and soft X-ray optics make it practical to use such sources as experimental tools for time-resolved X-ray science. Other possible generation techniques, such as laser-electron-beam scattering, promise to further expand the experimental capabilities in this area.
