Abstract: Some gage-equivalent forms (including the new ones) of the time-dependent Schrödinger equation for a hydrogenlike atom in a nonstationary electric field of a laser pulse are presented. These forms allow one to develop a perturbation theory for both small and rather large intensities of the electromagnetic field.
