Use of CARS spectroscopy for diagnostics in a high-temperature environment

Different applications of coherent anti-Stokes Raman scattering (CARS) in nonintrusive diagnostics at high temperatures are reviewed. Its application to small laboratory flames and large-scale (10 X 10 m) furnaces are described as well as probing in electric discharges. Finally, the potential of using pure rotational CARS and its applicability to flame measurements are described.
