We show that the significantlyenhanced conversion efficiency enabled by ultraslow propagation of pump waves has no directrelationship with the single-photon detuning, which is different from the FWM with a single EIT. Themost important feature is that our scheme is also capable of inhibiting and delaying the onset ofthe detrimental three-photon destructive interference that looks like a recent scheme [Phys. Rev.Lett. 91 (2003) 243902] and may be used for generating short-wave-length coherent radiation.展开更多

A detailed semiclassical study of the propagation of generated mixing and probe fields is demonstrated. The analytical dependence of the generated mixing field on the probe field and the respective detuning is predicted.
