Abstract：The system with 7 153.748-7-154.354 cm-1 line-pair based on tunable diode laser absorption spectroscopy (TDLAS) is designed for temperature measurement of premixed flat flame. Due to the weak absorptions, the signal-to-noise ratios (SNR) are low, and the relative deviation between TDLAS and thermocouple are larger. Therefore, the dual lasers TDLAS system with (7 185.597-(7 444.352+7 444.371) ) cm-1 line-pair, which is combined long path method, is developed for improvement of measurement accuracy. The result shows that the selected range will be broaden by using dual lasers, and the stronger line pair will be selected for improvement of SNR. Furthermore, combined the long path method, the relative deviation between TDLAS and thermocouple can be reduced from 10% to 5%.
