title: Competition between stimulated three-photon scattering and parametric four-wave mixing.
abstract: We show that destructive interference between the polarizations produced by three-photon scattering and parametric four-wave mixing suppresses the gain at the three-photon frequency under quite general conditions. The conditions for the suppression are discussed, and experimental verification in Na vapor is presented.
