Abstract

The problem of propagation of high-power femtosecond laser pulses in a self-focusing regime and formation of filaments is considered. Comparative analysis of key parameters of the filaments formed in a laser beam in two physically distinct media (atmospheric air and water) is carried out. It is established that the cardinal distinctions in optical parameters of water and air, and, first of all, in values of the Kerr coefficient, chromatic dispersion, and photoionization probability of molecules lead to changes in key characteristics of light and plasma filaments generated in the channel.
