摘要

Numerical analysis of a multiwave path gas-analyzer, based on a NH_(3)-laser pumped by CO_(2)-laser radiation, is performed for model detection of concentrations of a series of molecular species such as NH_(3), HCN, phosgene, NHO_(3), CO_(2), and H_(2)O. The potentialities of the gas analyzer and uncertainty of the gas concentration detection were estimated for a 4 km horizontal atmospheric path. The estimation took into account the absorption of laser radiation by the atmospheric aerosol and molecular gases under study and distortion of the laser beam due to atmospheric turbulence.
