Ultrafast time‐resolved X‐ray diffraction

Femtosecond laser‐generated plasmas emit ultrashort X‐ray pulses in the multi‐keV range, which allow the extension of X‐ray spectroscopy into the ultrafast time‐domain. We report here on the generation of such short X‐ray pulses and their application for time‐resolved diffraction as a means to directly study ultrafast structural dynamics in laser‐excited solids.
