We propose a scheme for creating coherent atomic superposition states via the technique of stimulated Raman adiabatic passage (STIRAP) in a Λ-type system where final states are composed of manifold of levels and the intermediate levels could be more than one level. If the pump pulses and Stokes pulses are kept in the same order of ordinary STIRAP, through the control the delay time between the Stokes pulses and pump pulse, we could create arbitrary superposition states in the manifold of levels.

During the STIRAP process, the intermediate levels will have notable population which is detrimental if these levels could decay to other levels through spontaneous emission. Here, we propose a novel method which could reduce the intermediate level population during the STIRAP process. A complete population transfer could be achieved in this modified STIRAP even if the intermediate level could decay to other levels.
