Abstract
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.
Highlights
Outlook The recent breakthroughs in attosecond “water window” X-ray sources open the door to game-changing applications
The combination of unprecedented time resolution with element-specific spectroscopy provides a unique opportunity for studying charge and nuclear dynamics in organic molecules and materials containing C, N, O, and other important elements and may help in understanding the charge transfer mechanism in solar cell materials
Transient-absorption spectroscopy measurements have been demonstrated in the water window with attosecond time resolution
Summary
Outlook The recent breakthroughs in attosecond “water window” X-ray sources open the door to game-changing applications.
