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 δ‐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.
