Stark-chirped rapid adiabatic passage [T. Rickes et al., J. Chem. Phys. 113, 534 (2000); A. A. Rangelov et al. Phys. Rev. A 72, 053403 (2005)] has been proposed as a laser scheme that allows the optical excitation of atoms or molecules with high quantum yields. The laser control proceeds via adiabatic passage assisted by dynamic Stark shifts. We propose several extensions of the scheme with alternative sequences, by frequency tuning or by repeating the pulse sequences, in order to achieve fine state selectivity within multilevel structures and adiabatic passage of quantum superposition states. The efficiency and selectivity of the schemes is compared with that achieved by other optical coherent methods.
