Abstract
Dual-broadband coherent anti-Stokes Raman scattering (CARS) spectroscopy of the Q(01)-branch of H-2 has been employed for thermometry in an atmospheri c-pressure hydrogen-oxygen flame. The aim was to investigate the applicabil ity of the technique for single-shot temperature evaluation and to analyse the precision of the measurements. The results are presented of temperature and relative H2 density mapping of the flame in the temperature range of 7 00-2800 K. The achieved precision of single-shot measurements was 3%-5%.
