Paper Abstract

The lidar complex of equipment based on TEA CO2 laser specially designed for atmospheric sensing, with automatic tuning on generation lines in the spectral ranges 9 - 11.3 and 4.5 - 5.6 micrometers has been described. Besides regular transitions 0001 - 1010 (0200), the laser is able to generate powerful (megawatt) pulses on hot band (011 - 1110) lines. Considerable extension of the spectral range to the short-wave region is attained due to effective TEA CO2 laser second harmonic generation in nonlinear crystals. Taking into the real potentialities of the lidar complex in hand, using a package of spectroscopic data HITRAN, computer simulation of atmospheric transmission has been made. On this bases, by the method of differential absorption a method has been elaborated for measuring small concentrations of a large number of gases, including especially dangerous atmospheric pollutants CO, C2H4, etc. This method was tried out on medium paths (approximately 1 km) in the real conditions of Minsk. Small (background) concentrations of a number of atmospheric gases have been measured.
