Pulse broadening in femtosecond x-ray diffraction

Abstract
Advances in femtosecond laser technology make feasible the generation of femtosecond x-ray pulses. An analysis of Bragg diffraction of subpicosecond x-ray pulses is presented. It is shown that the three-dimensional nature of the diffracting crystal grating and the finite size of the x-ray beam will lead to a considerable broadening of the diffracted femtosecond x-ray pulse.
