Abstract

The results of measure of the duration of a femtosecond laser pulse propagating in a mixture of dry air and water vapor (atmosphere) on a hundred-meter atmospheric track have been presented. Measurements have been made for a spectrally limited pulse and a pulse with initial frequency-phase modulation. A model for calculating the humidity and refractive index of a multicomponent medium for estimating the dispersion spread of an ultrashort pulse in the atmosphere has been discussed.
