Abstract
The computer simulation results on propagation of a few femtosecond pulses in dry and humid air are presented. Rapid spreading of such pulses is demonstrated. The propagation of a pulse with a negative initial chirp in dry and humid air is considered. A strong dependence of the minimum pulse width distance on air humidity is found.
