Abstract

The prototype of He-Ne / He-Xe laser system for methane detection using differential absorption of radiation backscattered from topographic targets is described. Using radiation of the wavelengths 3.39 μm and 3.51 μm, the measurement of CH₄ at the distance of 50 m was carried out. To increase the range and accuracy of measurement, the Cassegrain optics and lasers of higher power can be used. The lasers have four-channel construction structure and they are excited with RF current.
