Abstract: The feasibility of determination of the concentration of methane in air with the aid of an HCN laser emitting at the wavelength 337 μm was demonstrated under laboratory conditions. The method used is based on a change in the intensity of the output radiation of this laser associated with of a change in the methane content in air.
