Design study of time-preserving grating monochromators for ultrashort pulses in the extreme-ultraviolet and soft X-rays [PDF]

, 2017
The design of grating-based instruments to handle and condition coherent ultrafast pulses in the extreme-ultraviolet is discussed. The main application of such instruments is the monochromatization of high-order laser harmonics and free-electron-laser ...

Mapping Atomic Motions with Electrons: Toward the Quantum Limit to Imaging Chemistry [PDF]

, 2020
Recent advances in ultrafast electron and X-ray diffraction have pushed imaging of structural dynamics into the femtosecond time domain, that is, the fundamental time scale of atomic motion.

Melting and refreezing of zirconium observed using ultrafast x-ray diffraction

Physical Review Research, 2020
Ultrafast (130-fs) x-ray diffraction at the Linac Coherent Light Source has been applied to observe shock melting, which is driven by a rapid (120-ps) laser pulse impinging on a thin (few micrometers) bilayer of aluminum/zirconium.

Limitations of Structural Insight into Ultrafast Melting of Solid Materials with X-ray Diffraction Imaging

Applied Sciences, 2021
In this work, we analyze the application of X-ray diffraction imaging techniques to follow ultrafast structural transitions in solid materials using the example of an X-ray pump–X-ray probe experiment with a single-crystal silicon performed at a Linac ...

‘Ultrafast’ Extended to X-Rays: Femtosecond Time-Resolved X-Ray Diffraction

Zeitschrift für Physikalische Chemie, 2001
For a long time the capability to perform measurements with femtosecond time-resolution belonged exclusively to the domain of optics. However, in the last few years laser-driven X-ray sources have been developed which enable femtosecond time-resolution to be extended to the X-ray regime.

Detection of Nonthermal Melting by Ultrafast X-ray Diffraction

Science, 1999
Using ultrafast, time-resolved, 1.54 angstrom x-ray diffraction, thermal and ultrafast nonthermal melting of germanium, involving passage through nonequilibrium extreme states of matter, was observed. Such ultrafast, optical-pump, x-ray diffraction probe measurements provide a way to study many other transient processes in physics, chemistry, and ...
