Growing interest in precise measurements of methane concentration and distribution in the Earth’s atmosphere is stimulating efforts to develop LIDAR systems in the spectral region of 1.65 μm utilizing Path Differential Absorption techniques. The key element of such systems is a tunable high energy transmitter operating in the vicinity of a methane absorption line. We developed a novel laser source meeting these system needs using in-band pumping Q-switched solid state lasers (SSLs) based on Er-doped active media. We demonstrated a feasibility to measure methane line at 1651nm.
