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.
