Abstract
A differential absorption lidar (DIAL) system based on a tunable solid-state Ti: sapphire laser was developed for nitrogen dioxide monitoring in the blue region. An efficient blue generation scheme was realized by the sum-frequency mixing between a Ti: sapphire laser and another Nd: YAG laser. In order to reduce the effect of the atmospheric condition change, the laser wavelength was switched on-and-off resonant in every shot, and the data were averaged over a large number of shots. As an example of measurement, a concentration distribution of nitrogen dioxide from diesel engine emission was measured in the good agreement with an insitu measurement.
