Highly sensitive detection of CO2 molecule using near-infrared diode laser absorption spectroscopy
Observation of CO2 by combined near-infrared tunable diode laser with direction absorption spectroscopy and wavelength modulation spectroscopy around 1.31 μm was presented. A minimum detectable absorption line intensity of 3.769 ×10-27 cm-1/(molecule·cm-2) was achieved at the pressure of 5 Torr, with a corresponding SNR of 16.8.
