Аннотация: We present the results of sensing of the atmosphere in the condition of a transition 'continent - ocean' zone by means of gigawatt femtosecond pulses of the fundamental and second harmonics of a Ti: sapphire laser. In the regime of multi-frequency sensing (supercontinuum from the fundamental harmonic) the emission lines of the first positive system of the nitrogen molecule B 3? g - A3?u + have been recorded, while the sensing using of the second harmonic have revealed the possibility of detecting the lines of Raman scattering of nitrogen (?= 441 nm). The intensity ratio of the line of Raman scattering of nitrogen and the line of elastic scattering at the wavelength of l?= 400 nm amounts to 5.6 ? 10-4. © 2014 Kvantovaya Elektronika and Turpion Ltd.
