Abstract

This paper discusses the possibility of using a laser system with parametric light generation based on a nonlinear KTiOAsO₄ crystal for lidar probing of the atmosphere in the 3–4 μm range. A combined technique has been developed for lidar measurements of the gaseous components of the atmosphere, using the differential-absorption method (DAM) and differential optical absorption spectroscopy (DOAS). The DAM–DOAS technique has been tested in a numerical experiment to estimate the possibilities of lidar probing of minor gaseous components of the atmosphere.
