Abstract
In a two-photon resonant three-level system, population can be trapped in a noninteracting superposition state. We demonstrate that this phenomenon persists in a multilevel system in which the final state is replaced by a number of nondegenerate states. The magnitude of the trapped population depends only on the matrix elements between the pair of two-photon resonant levels and the intermediate level. A dressed-state approach is also considered.Keywords
