Lidar sensing atmosphere by gigawatt femtosecond laser pulses in the continent-ocean transition zone

摘要

The results of lidar sensing of the atmosphere in the continent-ocean transition zone obtained on three modifications of a femtosecond lidar: elastic scattering lidar, Raman lidar, white light lidar are discussed. In the mode of multi-frequency sensing (supercontinuum from the fundamental harmonic), the emission lines of the first positive system of the nitrogen molecule are registered. Comparisons of obtained data with the results of lidar sensing using of nanosecond laser pulses are presented.
