Abstract

A differential absorption lidar system was designed on the basis of parametric light generation with nonlinear KTA and KTP crystals, which allow turning laser radiation in the near- and mid-IR spectral regions. Lidar echoes were experimentally detected in the 1.8–2.5 and 3–4 μm wavelengths ranges. The results of first in situ measurements of the methane concentration in the mid-IR are given.
