Development of a Ti:sapphire DIAL system for pollutant monitoring and meteorological applications

A mobile differential absorption lidar system with SHG of Nd-YAG pumped Ti:Sapphire laser has been developed and tested. Mixing between Ti:Sapphire and Nd-YAG fundamentals extends the wavelength range to UV–vis region (250–480nm), which is ideal to monitor tropospheric pollutants. Preliminary water vapor profiles in the near IR region (in our case 800–900nm) are presented and discussed.
