Abstract

A simulation of remote atmospheric gas analysis in the spectral range near the wavelength of 1572 nm has been performed. The characteristics of a narrow-band thermostable continuous laser diode with an output power of ≤15 mW have been experimentally studied, and the possibility of tuning the laser diode wavelength both within a separate isolated CO2 absorption line and from line to line in the CO2 absorption band has been shown. The possibility of using a laser diode for further work on the creation of a lidar sensor for studying the CO2 content in the atmosphere has been shown.
