摘要

The experimentally observed special line-shape induced by the interaction between two counter-propagating equal- frequency fields and an Y-type four-level system with two mixed upper levels has been analyzed theoretically. Serious line-shape variations of the two-photon transitions due to the quantum interference are discussed and predicted.
