  • We present an experimental study of cw degenerate four-wave mixing (DFWM) in Doppler-broadened rubidium atoms coupled by an additional coherent field. The coupling field and the DFWM fields were arranged in a Λ-type configuration from the rubidium [Formula Presented] transitions. We found that the presence of the coherent coupling field modifies the DFWM emission:mfat lower intensities of the coupling field, the DFWM emission is enhanced; at higher intensities of the coupling field, the DFWM is reduced. The observed effect of the coupling laser on the DFWM emission may be explained by the direct competition between the resonance-enhanced two-photon Raman scattering and the optical-pumping-enhanced DFWM emission. © 1996 The American Physical Society.
