The development of a differential absorption lidar (DIAL) system in the mid-IR region for the detection and monitoring of light hydrocarbons is presented. Two lithium niobate optical parametric oscillators provided the signal and reference wavelengths. With the aid of a retroreflector, the system detected 0.63 ppm of propane and 0.05 ppm of methane in the atmosphere at a greater than 1 mile range in the controlled release tests. Subsequently, the system mapped a petroleum deposit in eastern New Mexico.
