Аннотация:Experimental and theoretical investigations into the propagation of high-power laser pulses in the atmosphere are reviewed. The process of filamentation of a high-power femtosecond laser pulse is considered as evolution of the static and dynamic instability of the light field under conditions of strong nonlinearity. The process of initiation of a filament bunch in a TW-power pulse of a femtosecond lidar has been numerically studied, and the results of this study are presented. The influence of the linear dispersion of the group velocity in air on the spatiotemporal intensity distribution of a high-power femtosecond laser pulse is analyzed.
