A scheme of multiplex nonresonant pump four-wave mixing (NRP-FWM) process was discussed. The process was accomplished with two high-intensity pump beams detuned far from the resonance of the sample under investigation and a weak resonant probe beam. A single-broadband probe beam was used for the multiplex experiment to detect the electronic swan band spectrum of C2 molecules in a premixed acetylene-oxygen flame. It was found that the signal level at which the NRP-FWM starts to show saturation is about 250 times higher than in the case of the Degenerate FWM (DFWM).
