We present the second phase of our work in project LISATNAS devoted to design the differential absorption lidar (DIAL) based on the mid-infrared (IR) tunable Optical Parametric Oscillator (OPO). Generation of tunable mid-infrared laser radiation using a two stage tandem OPO was demonstrated. The first stage was based on the nonlinear KTP crystal and produced up to 45 mJ of 1.57 μm radiation, while pumped by a commercial Q-switched Nd:YAG laser. The quality of signal beam was improved by the use of unstable resonator. The AgGaSe2 crystal was used in the second stage OPO. Idler energies up to 1.2 mJ were generated in this stage within tuning range from 6 to 12 μm. The receiver consisted of a 250 mm gold mirror telescope, pyroelectric detector with control electronics. Preliminary field test results for detection of H2O using a retroreflector are presented.
