针对当前可调谐半导体激光器吸收光谱(TDLAS)技术中调谐范围、调谐时间以及系统复杂性方面存在的不足，提出了利用激光器模块中的热电制冷器(TEC)和负温度系数(NTC)热敏电阻等元件对激光二极管(LD)进行温度宽谱调谐的方法，并在快速温度调谐过程中精确计算激光器的辐射波长。利用温度调谐二极管吸收光谱技术在3 s的时间内测得了CO2气体在6320~6336 cm-1波段的高分辨率吸收光谱。在此波段共测得8个较强吸收线。将得到的光谱参数与HITRAN 2008中的数据比较，吸收线位置、线强以及半峰全宽（FWHM）的偏差分别小于1%，3%以及6%。另外，测得的14条较弱的吸收谱线也与谱库中的谱线参数吻合。

There are some disadvantages in the current tunable diode laser absorption spectroscopy (TDLAS), such as tuning range, tuning time and system complexity. A fast temperature tuning method of broad spectrum is developed and the dynamic wavelength of the laser is calculated precisely during the temperature tuning by means of thermo-electric cooler (TEC) and negative temperature coefficient (NTC) thermistor integrated in laser diode module. The spectral measurements of CO2 absorption lines from 6320 to 6336 cm-1 are performed at room temperature by using fiber-coupled distributed feedback (DFB) diode laser operating at 1.58 μm with measurement time less than 3 s. Eight strong absorption lines are obtained and are compared with HITRAN 2008 database, which shows that the deviations of absorption line positions, line strength and full-width at half-maximum (FWHM) are less than 1%, 3% and 6%, respectively. Additionally, the corresponding spectral parameters of 14 weak absorption lines are very consistent with those in HITRAN 2008 database.
