Abstract
Ozone concentrations in an altitude range of 3-28 km were determined with a resolution of 1.5 km by a differential absorption lidar (DIAL) based on excimer lasers. Emission from a XeCl laser (308 nm) and stimulated Raman scattering (SRS) of CH4 (S2: 290.4 nm) and H2 (S1: 277 nm, S2: 313 nm) pumped by a KrF laser was used. It is shown that excimer lasers and SRS pumped by excimer lasers (Excimer-SRS) are more useful and practical than frequency-doubled dye lasers in DIAL observation of atmospheric ozone, because Excimer-SRS has a simple configuration, high average power and a high repetition rate.
