A four-wave difference mixing signal has been observed for what is, to our knowledge, the first time, in sodium in a methane–air flame. The experimental conditions used to observe the signal in the flame are reported. An explanation of the observed signal in terms of near two photon resonant difference four-wave mixing is proposed.
