Abstract
Modifications of temporal parameters of ultrashort laser pulses (USP) with intensity more than 1012 W/cm2 and duration not less than 700 ps, reflected from boundary "air-plasma" and emitted by the neodymium superregenerator are investigated. We explain shortening of pulses by Doppler effect originating in plasma that results in occurrence in it of properties of an abnormal dispersion. Designed circuits of a superregenerative amplification of a USPs appeared fit for examination of high-speed processes in the plasma excited in air, and also for production of polyatomic carbon compounds (fullerenes).
