Summary:We consider adiabatic interaction of quantum systems with electromagnetic field in the presence of various dissipation processes. As it is known that in the presence of large intermediate detunings any n-level system can be reduced to an effective two-level system, we chose the two-level model as the basic model for a detailed analytical study. We demonstrate the possibility of reducing losses due to dephasing and non-adiabatic corrections by choosing an appropriate design of time-dependent interaction parameters. Simple analytical expressions are derived for both cold and hot atomic ensembles. The results obtained for the two-level system are applied to a three-level system by using the method of adiabatic elimination. Efficient population transfer is shown despite the relatively high dephasing rates.
