Sub-femtosecond precision measurement of relative X-ray arrival time for free-electron lasers

Christoph Peter Hauri, Christoph Bostedt

Today's brightest coherent X-ray sources, X-ray free-electron lasers, produce ultrafast X-ray pulses for which full-width at half-maximum durations as short as 3 fs have been measured(1). There has been a marked increase in the popularity of such short pul ...
