NAOMI GAZL: A Multispecies DIAL Tested on the TADI Gas Leak Simulation Facility

We report on a direct detection differential absorption lidar (DIAL), designed for remote detection of CH4 and CO2 . The system is based on a single-frequency optical parametric oscillator/amplifier system, tunable in the 1.57-1.65 µm range. The DIAL system, called NAOMI GAZL, was tested on a controlled gas release facility in October 2018.
