Abstract

A differential absorption lidar (DIAL) system, based on a tunable solid-state Ti:sapphire laser, was developed for nitric oxide monitoring in the UV region. The UV light was generated through second-harmonic generation (SHG) of sum- frequency mixing between a Ti:sapphire laser, pumped by the SH of a Nd:YAG laser, and the fundamental of a second Nd:YAG laser. The output pulse energy of 4 mJ at 226.8 nm with 2 micrometers linewidth was achieved. As a demonstration of DIAL capability, the spatial distribution of nitric oxide emission from a diesel engine was investigated. The detection error achieved was +/- 0.05 ppm up to a distance of 180 m, with the spatial resolution of 20 m.
