Concept of a broadband near- and mid-IR lidar

The results are presented of measurements of the energy parameters of an output channel of an experimental setup for the gas analysis in the spectral ranges 1.8–2.5 and 3–4 μm with a KTP- and KTA-based OPO lidar. The lidar measurements of trace gases in the spectral range 1.8–2.5 μm are simulated. Echo signals of the broadband lidar in the above ranges are experimentally detected.
