Abstract

One of the actual problems of the multi-frequency laser remote sensing is the using of the self-action phenomena of pulsed femtosecond laser radiation. When femtosecond laser radiation propagates in the atmosphere, both the transformation of the spectral and spatial characteristics of the radiation dispersion and the pulse duration occurs. The effect of atmospheric air dispersion on the duration of a femtosecond pulse propagating in the atmosphere is discussed via the results of experiments. The fact of compensating of the dispersion spreading of the pulse duration in air by its temporary “compression” under the influence of a change in the phase modulation index in an optically active impurity is not excluded.
