Abstract
Using Schr6dinger-Maxwell formalism, we propose(FWM) scheme for the generation of coherent lightand analyze a continuous-wave four-wave mixingin a six-level atomic system based on electromag-netically dual induced transparency. We derive the corresponding explicit analytical expressions for thegenerated mixing field. We find that the scheme greatly enhances FWM production efficiency and isalso capable of inhibiting and delaying the onset of the detrimental three-photon destructive interferenceby choosing the proper decay rate in the second electromagnetically induced transparency (EIT) process.In addition, such an optical process also provides possibilities for producing short-wave-length coherentradiation at low pump intensities.
