Four-wave mixing is studied in a Na-seeded flame in the regime of strong saturation of the Na D-line transitions. The output frequency differs from that of the input lasers so that spectral discrimination can distinguish the mixing signal. Scans of the D2 resonance with another laser set at the D1-line resonance reveals two resonances corresponding to the D2 resonance and the frequency difference of the D levels. The mixing efficiency at the D2 resonance increases with the detuning of the D1 resonance. The frequency difference resonance is weak because of interference between multiple coherent pathways.

Doubly resonant four-wave mixing has been used with two lasers set for resonance with the two Na D-line transitions to perform elemental analysis with a Na-seeded flame. The method is analogous to phase-conjugation methods where all lasers have the same frequency. Strong saturation effects and dynamic Stark splittings are observed and used to optimize the mixing efficiency. A nonperturbative theory is presented and shown to describe the experimental results.
