The authors have performed coherent anti-Stokes Raman scattering (CARS) measurements of acetylene in a laminar CH/sub 4//C/sub 2/H/sub 2//air flame. The acetylene concentration was determined from the ratio of the resonant acetylene CARS signal to the nonresonant background CARS signal. The resonant and nonresonant signals were detected separately on each laser shot using polarization analysis and a two-channel detection system. The flame temperature profile was determined from fits of nitrogen CARS spectra. Experimental acetylene CARS spectra are compared with theoretical spectra.
