摘要：
When the intermediate level in a ladder-type atom is coupled with a higher-excited and a ground levels by two control fields, there appear double electromagnetically induced transparency windows in the two-photon absorption spectra. The effects of the Rabi frequencies and the detunings for the control fields on the two-photon absorption spectra are also investigated. Finally, the explanations of these phenomena and the conditions of the absorption minimums are given by using the dressed states. (c) 2005 Elsevier B.V. All rights reserved.
