Abstract

Degenerate four-wave mixing is a nonlinear technique in which the interaction of the input beams with a nonlinear medium generates a fourth coherent signal beam. To achieve a resonantly enhanced coherent interaction between the input beams and the medium, the frequency of all three beams ω must be resonant with art atomic or molecular transition. Infrared degenerate four-wave mixing employs rovibrational transitions for resonant enhancement.
