Abstract

We report a new differential absorption lidar technique for measuring simultaneously the concentrations of NO and NO2 in the atmosphere. The technique is based on the correlation of the 450-nm absorption band of NO2 and 227-nm absorption band of NO by frequency doubling. This performance has been allowed by the advent of a new and highly efficient frequency doubling crystal: the β-BaB2O4. A test experiment on a NO/NO2 emitter has been performed, demonstrating the efficiency of the technique. The detection limit is estimated to be ~1 ppm · m for NO2 and 100 pp · m for NO. The range of measurement is limited to 1 km, due to the strong UV Rayleigh scattering and O2 absorption.
