Abstract

We have developed a 1.6 μm carbon dioxide ( CO 2 ) differential absorption lidar utilizing a quasi-phase-matching optical parametric oscillator (OPO) and a photon-counting detector. The operating wavelengths were chosen based on their low interference from water vapor and low temperature sensitivity. The online wavelength was in the ( 30012 0001 ) band of CO 2 , which was insensitive to atmospheric temperature. The established OPO laser achieved a 10 mJ , 200 Hz repetition rate at the online and offline wavelengths. Our observations confirmed the statistical error of 2% with 5 h of accumulation for the CO 2 density profile less than 5.2 km . Also, the statistical error of 1% at an altitude of 2 km was demonstrated. The results of the vertical CO 2 concentrations acquired using a 1.6 μm wavelength are presented.
