The accuracy of simplified CARS (Coherent Anti-Stokes Raman Spectroscopy) temperature measurements has been studied. The proposed CARS method provides the instantaneous temperature determination with the quick measurement of the intensity ratio of N_2 CARS spectra by the use of a specially prepared monochromator, two photomultipliers and data processor including a circuit for sampling mechanism, an A/D converter, and a personal computer. Various causes and their contributions to the measurement errors introduced in these instruments have been evaluated experimentally. In the static hot air experiment, the standard deviation characteristic of the total error was 55 K for the mean temperature 928 K and 1000-shots. It is recommended that 500 laser-shots be used in order to obtain a reasonable mean temperature.
