Abstract

The extraction of temperatures from experimental CARS spectra is discussed and demonstrated in an electrically heated over and a low-pressure flame. The present work is focused, in particular, on how the precision of CARS thermometry is limited by the accuracy with which the experimental parameters are known, on characteristics of the diode-array detector, on saturation effects due to stimulated Raman scattering and on the influence of spectral resolution on precision and accuracy.
