A new multiparametric lidar system spanning from UV to mid IR is presently under testing. The system is based on two Optical Parametric Amplifier (OPA) lasers pumped by a Nd:YAG laser operating at a maximum pulse repetition rate of 100 Hz. OPA lasers represent a new design for coherent radiation sources continuously tunable in the UV-IR range. The large range of tunability of OPA lasers allows to perform Differential Absorption Lidar measurements in a spectral region where most of atmospheric pollutants display absorption lines. The system has been designed to deliver simultaneously in the atmosphere the Nd:YAG fundamental and its harmonics (II and III) as well as the four output beams of the two OPA lasers. The return signals, collected by means of two Newtonian telescopes, can be used to retrieve information on: atmospheric aerosols, water vapor and pollutants concentration, atmospheric temperature, density and transmissivity profiles. In this paper a detailed description of the system is reported. Moreover, some results obtained by a multiparametric system (based on a Nd:YAG pumped dye laser) are reported to show the capabilities of a multiwavelength lidar system.
