Experimental study of the characteristics of the propagation of femtosecond radiation: results of the dispersion spreading

A series of laboratory and full-scale experiments on the propagation of high-power terawatt radiation on the basis of a femtosecond stand of the IAO SB RAS have been carried out. The problem of the spreading of femtosecond pulses in air is considered. The results of the investigation of dispersion spreading of pulses of femtosecond duration are presented.
