X-ray diffraction in crystals in the presence of laser-induced dynamic gratings

Abstract

A theory of x-ray diffraction (XRD) in the presence of optically induced superlattices has been developed both in the case of thin, non-absorbing and thick crystals. The main features of this process have been analysed. Experimental requirements to observe coherent influence of the optically induced superlattices on the process of XRD were formulated. It was shown that the resonance influence of the optically induced dynamical gratings on XRD can be observed under experimentally feasible conditions.}
