AbstractA technique termed "coherent, anti-Stokes Raman spectroscopy" (CARS) has been developed at the Combustion and Carbonization Research Laboratory of CANMET's Energy Research Laboratories for the measurement of temperature and species concentration. The advantages of this technique over conventional probing methods are improved temporal and spatial resolution; it is nonintrusive and turbulence parameters can be determined. This report discusses the theoretical basis for such a technique and some of the practical considerations involved in the optical arrangement. To apply this technique successfully, it was necessary to develop sophisticated software and hardware. The incorporation of these and the optics into a CARS system is discussed, together with the theory of its application.
