Degenerate four-wave mixing temperature measurements in a flame.
Multiplex degenerate four-wave mixing is performed by using OH radicals in an atmospheric-pressure hydrogen-oxygen flame. The ratio of the signal intensities from two OH transitions simultaneously pumped by a single laser pulse is used to determine the local instantaneous flame temperature.
