Most of gaseous materials show characteristic optical absorptions, especially in the mid-infrared (2-25¿m) band. The optical fingerprints of different gases have made the spectral absorption a unique method of gas analysis. The tunable diode laser absorption spectroscopy (TDLAS) method use a compact single mode diode laser tuning over an interested wavelength range swiftly can fulfill the function of spectroscopy scan. In this talk the TDLAS experiments using home made mid-infrared diode lasers for gas sensing are represented, and various effects affecting the performance of the sensor have been discussed.
