Development of atmosphere lidar sounding methods with femtosecond impulses

Data were obtained for lidar sounding of the atmosphere in the continent-ocean transition zone by three modifications of a femtosecond lidar, based on a titanium-sapphire laser with chirped power amplification: elastic scattering lidar, Raman scattering lidar, and white light lidar. In the lidar mode of white light, the emission lines of the first positive system of nitrogen molecules were registered. A comparison of the obtained data with the results of lidar sounding using laser pulses of nanosecond duration is presented.
