摘要：

The absolute absorption spectrum intensities of carbon dioxide sample have been recorded with a tunable diode laser spectrometer in the spectral range 6506-6520 cm(-1), which is suitable for the in situ sensing of carbon dioxide in the lower stratosphere, and were studied using a commercial telecommunication-type diode laser. The intensity of the weakest line we detected in this experiment is 9.116 x 10(-27) cm(-1)/(molecule-cm(-2)) at a pressure of 0.35 torr, and the corresponding absorption is 1.96 x 10(-6) with SNR of 2.67.
