摘要：
A relatively simple technique of analytic calculation based on the method of quasienergies is proposed, which allows all necessary conditions for lossless short pulse propagation in a multilevel atomic medium to be revealed. The method is illustrated for three- and five-level atomic systems. The dynamics of pulse propagation in a multilevel medium is demonstrated for the case of a W-system of levels. The conditions for adiabatic interaction in a medium are obtained.
