OPOs for standoff gas sensing

The presentation will especially focus on our latest development on high energy infrared emitters (mJ level) for long range (km) differential absorption LIDAR (DIAL) applications. These developments either address the 1.6 μm – 2.0 μm range for the detection of greenhouse gases (CO2, CH4, and H2O), and the 8.0 μm – 12 μm region for the detection of toxic agents. Most of these systems were implemented as transportable optical benches that were deployed for outdoor field test in representative facilities. Emitters’ performances, LIDAR instrument capabilities, as well as experimental demonstration results will be discussed during the presentation.
