Paper Abstract

We describe a new development of differential absorption DIAL spectrometric system based on the mid-infrared tunable Optical Parametric Oscillator (OPO), pumped by compact Q-switched lasers. Mobile LIDAR was assembled in the truck and is devoted for selective pollutant analysis in the distance range extending from hundred of meters to a few kilometers. A reliable cascade mid-IR generation scheme was developed. Pulse energies up to milijoule in mid-IR (λ=8-12 μm) have been already obtained using nonlinear AgGaSe2 crystal. The collinear optical scheme with 25cm (10inch) gold mirror telescope, MCT thermoelectrically cooled detector with control electronics was tested at 250m optical length and currently is under further development.
