Abstract

A ground-based differential absorption LIDAR system has been development and using in several field tests. The system is based on the well-established configuration of a Nd:YAG laser pumping a dye laser, working in the ultraviolet spectral range with the following characteristics: Emission of 8 mJ/pulse laser radiation at the spectral range 290-310 nm (Dye: Rh 610) and 20 mJ/pulse in the range 430-460 nm (Coumarin 450), divergence ≤0,1, linewidth, 2,5 cm-1 and beam diameter of 50 mm.
