高功率超快短波和中波红外激光器的最新进展使水窗口内外的气相高次谐波产生(HHG)成为可能，以及凝聚态物质中HHG的演示。从这个角度出发，我们讨论了从气相HHG产生和表征软X射线脉冲和从固态HHG产生极紫外(XUV)脉冲的最新进展和未来趋势。然后，我们讨论了它们在原子、分子和凝聚态物质中电子和核动力学的时间分辨研究中的当前和潜在的应用。
Recent progress in high power ultrafast short-wave and mid-wave infrared lasers has enabled gas-phase high harmonic generation (HHG) in the water window and beyond, as well as the demonstration of HHG in condensed matter. In this Perspective, we discuss the recent advancements and future trends in generating and characterizing soft X-ray pulses from gas-phase HHG and extreme ultraviolet (XUV) pulses from solid-state HHG. Then, we discuss their current and potential usage in time-resolved study of electron and nuclear dynamics in atomic, molecular and condensed matters.
