Abstract
The differential absorption method is the best one from the point of view of its potentialities in applications to solving the problems of sensing atmospheric gaseous pollutants. The middle IR spectral range from 2 to 14 micrometers is most attractive for measurements since well-resolved absorption spectra of almost all the atmospheric gases are observed here. This paper presents some results of monitoring several trace atmospheric constituents, including CO, C2H4 and NH3 using a gas analyzer, based on the use of two CO2 lasers and a set of frequency converters. The gas analyzer with a discretely frequency-tuned CO2 laser was taken as the basic device for this study. Use of a ZnGeP2 monocrystal for frequency doubling enables one to measure CO concentration in addition to concentrations of ethylene, water vapor, ammonia under field conditions.
