Abstract
In degenerate four-wave mixing, the interaction of three input beams with a nonlinear medium generates a fourth coherent signal beam. The coherent nature of the signal beam offers several advantages in minor species detection in hostile or luminous environments. Prior experiments using ultraviolet input beams to detect OH or NH radicals in flames1,2 and NO as a low pressure gas3 readily demonstrated good background discrimination and high signal collection efficiency.
