An electromagnetically induced transparency (EIT)-enhanced four-wave-mixing (FWM) scheme was analyzed and showed that the FWM field can be efficiently generated with weak pump fields. The scheme uses the resonant intermediate states and one more laser field to facilitate the resonant two-photon and three-photon couplings. Due to the EIT-induced suppression of the two-photon and three-photon absorptions, an additional increase of the FWM efficiency by several orders of magnitude can be obtained.
