Short X-ray pulses in a Laue-case crystal.
The short X-ray pulses coming out of a SASE FEL (self-amplified stimulated-emission free-electron laser) have stimulated a closer inspection of the response of a crystal reflection to them. After a short collection of formulae taken from the dynamical theory of X-ray diffraction, the response to a delta-pulse reflected by a Laue-case monochromator crystal is investigated. In contrast to the already discussed Bragg-case monochromator, a two-dimensional analysis is required.
