Abstract: It is shown that not only multicycle resonant pulses with zero electric area, but also nonresonant unipolar pulses can be used to efficiently excite quantum transitions in a medium. Arguments are presented in favor of the advantages of unipolar pulses for excitation of quantum systems in comparison with resonant radiation. A simple relationship has been found showing that in order to compare the effects of unipolar half-cycle and resonant multicycle pulses on atomic systems. It shows that it is necessary to compare the electric area of a unipolar pulse and the area of the envelope of a bipolar pulse, rather than their energies.

Keywords: unipolar pulses, electric pulse area, pulse area, extremely short pulses, attosecond pulses.
