Abstract

The purpose of this paper is to report our results on the detection and spectroscopic parameters of carbon monoxide, carbon dioxide and sulfur dioxide using high resolution linear diode laser spectroscopy with pulsed tunable PbS1-xSex homolasers. The parameters of pulsed diode lasers used in spectroscopy for various gases are discussed. The application of the diode laser spectrometer for CO gas detection at ppm level illustrates the sensitivity of the equipment.
