Abstract

We report our research on the development of a gas detection system for environmental application. The CO2 concentration of a remote site is detected with near-infrared laser spectroscopy. Light from a thermal-tuning DFB laser, whose wavelength is close to 1.57 μm, is delivered to/from the remote gas cell via silica optical fiber. The low transmission attenuation of 0.2 dB/km promises long distance CO2 sensing in the length of the gas cell in our experiment is 20 cm only, and detection accuracy of CO2 is 1%.
