Abstract:

Laboratory experiments with a first-overtone CO laser are performed to simulate a lidar system. The trace remote sensing scheme of atmospheric gases (nitrous oxide and methane) at emission lines of the pulsed first-overtone CO laser is tested using topographic target and receiving telescope. Results of the measurements of absorption of the first-overtone CO laser operating at 20 selected emission lines in gas mixtures with the gases studied at various configurations of the experimental scheme are presented.

Keywords:

first-overtone CO laser, gas analysis, atmosphere, differential absorption
