Popis:	The wave function of an electron interacting with a finite-range potential and an intense low-frequency laser pulse is analyzed within the adiabatic approximation. The closed analytic form for the wave function, which includes the rescattering corrections, is obtained with quasiclassical accuracy for an electron in both the initial bound and continuum states. We discuss the parametrizations of amplitudes of fundamental strong-field processes in terms of laser and binding-potential parameters. Based on the analytic results for the adiabatic wave functions, we develop the perturbation theory in an additional weak field. The modification of high-order harmonic generation amplitude caused by a weak extreme ultraviolet pulse is discussed in the first order of the perturbation theory.
