Inverse Compton scattering dubbed “light undulator” is a known source of x-ray radiation, bright and intense. Among the perspective directions of research one of the most significant is idea of Debus with co-authors: to use the laser pulse with skew front to increase the time of interaction of the electron and photon beams. The corresponding calculations were performed within classical electrodynamics. Here, we calculated this process in the terms of luminosity within quantum electrodynamics. Our results show that the condition suggested by Debus et al. for the maximal intensity will not result in the number of the scattered photons compared with the conventional collinear orientation of the fronts.
