Abstract

Degenerate four-wave mixing (DFWM) is a technique that shows great promise for sensitive measurements of transient gas-phase species. However, much research is required on some fundamental aspects of the physics of the technique, such as collisional and laser intensity effects, before DFWM can be applied quantitatively in a wide range of chemically-reacting media such as flames and plasmas.
