| 摘 要： | 用DFB（分布反馈）半导体激光器结合波长调制吸收光谱技术观测了CO2在1.31μm附近的泛频吸收光谱，并获得的相应的光谱参数（如：谱线位置，谱线强度以及自加宽系数），同时发现了15条弱的新谱线。在665 Pa压力下，本实验可探测的最弱谱线是2.25163′10-27 cm-1/(molecule×cm-2)，相应的吸收是3.88′10-8。

| Abstract: | Fifteen new absorption lines were observed when studying CO2 absorption spectroscopy by wavelength modulation technique with a distributed feedback laser. The overtone spectra of CO2 around 1.31μm and the corresponding spectral parameters (i.e. positions, intensities, self-broadening coefficients) are presented. The intensity of the weakest line detected is 2.25163×10-27cm-1/(molecule·cm-2) at the pressure of 667Pa, with a corresponding absorption of 3.88×10-8. |
