Longwave infrared lidar based on parametric sources for standoffdetection of gaseous chemicals

• We report on a longwave infrared lidar, tailored for detection of chemical warfare agents in the gaseous phase. The emitter is based on single-frequency 2 μm parametric oscillator/amplifier systems followed by a ZnGeP2 downconversion stage.
