Degenerate four-wave mixing is used to produce two-dimensional images of OH distributions in atmospheric-pressure flames. The phase-conjugated from single laser pulses exhibit excellent signal-to-noise ratios and illustrate that degenerate has outstanding potential as a multidimensional diagnostic for combustion environments.
