The three-photon resonant nondegenerate six-wave mixing via quantum interference

摘要

We study the quantum interference in three-photon resonant nondegenerate six-wave mixing (NSWM) in a five-level system in which the middle level of six-wave mixing and other level are coupled by a strong laser field. The coupling field-dependence of the NSWM signal intensity and the spectrum of the NSWM with a coupling field are discussed. We find that in the presence of a strong coupling field, the three-photon resonant NSWM spectrum exhibits Autler-Townes splitting, which reflects the levels of the dressed states. It also leads to either suppression or enhancement of the NSWM signal.
