Paper Abstract

A CO2 laser-based DIAL system has been developed for mapping vapor plumes. The DIAL system is composed of two home-made twin TEA CO2 lasers in self filtering unstable resonator. The receiving system is based on a Newtonian telescope with a 40 cm diameter that acquires the backscattered signal with a cooled HgCdTe detector on the focal plane. The signal is acquired by a VXI system and stored in the memory of a personal computer. The laser pulse is transmitted and received by a scanner module. Our first measurements indicated some disagreement between theory an practice. To resolve these problems in our fixed station we had to modify many aspects relating to the optical emission and performance of the station. The measurement have been made on water vapor and ozone. After a careful study of the experimental result we have decided to build a mobile lidar station.
