Abstract

ABSTRACT A new scheme providing self-compression of femtosecond laser radiation upon filamentation of a collimated beam in argon at a pressure of ~0.8 atm is experimentally realised. Pulses with the initial duration of 55 fs were compressed down to 8 fs, the peak power of the compressed pulse exceeding 20 GW.
