N2 - Tunable Diode Laser Absorption Spectroscopy ( TDLAS) can offer significant advantages for non-intrusive and in-situ measurement of temperature in combustion environments by using two-line technique. In the present work, with regard to the typical hydrocarbon combustion environment with the temperature range 1 000 K ~ 2 500 K, transitions of water vapor are simulated and analyzed by using HiTRAN database in the spectral region of distributed feedback(DFB)diode laser(1.25 μm ~ 1.65 (μm).The result shows that 7 153.748,7 154.354 cm1 line pair can satisfy the modulation range of a single diode laser,and has advantage of anti-interference and sensitivity for high temperature combustion gases. Therefore, a single laser temperature TDLAS sensor basing on 1 397 nm diode laser is designed and applied to measurement of temperature in flat flame burner. Comparison with thermocouple measurements, the maximum relative difference is less than 10%.
