Abstract

The problem of the propagation of a femtosecond laser radiation in the atmosphere remains relevant in the application to the problems of remote sensing. When radiation propagates in a multi-component dispersive medium, for example, atmosphere, two important facts are occurred. The first is the transformation of the spectral and spatial characteristics of the radiation. The second is the dispersion modification of the duration. The results of experiments to take into account the dispersion effect of a multi-component medium (atmospheric air) on the duration of a femtosecond wave packet propagating in the atmosphere are discussed.
