The interference peculiarities of absorption and emission of external laser field quanta by a spatially narrow electron wave packet during its scattering at a potential center are considered. The angular and energy distributions for an electron due to scattering in a laser field are obtained and analyzed within the framework of the perturbation theory based on interaction with the potential center. A mechanism of effective heating of electrons produced by the ionization with intense external laser field is found. It is shown that different regimes of laser-stimulated Bremsstrahlung can be distinguished in dependence on scattering time. The regime of "fast" scattering is found to be responsible for high energy plateau formation in electron spectra after ionization.
