This paper introduces and discusses the main aspects of ultrashort laser pulse filamentation
in various transparent media such as air (gases), transparent solids and liquids. The …

Investigation of coupling mechanisms between the troposphere and the ionosphere requires
a multidisciplinary approach involving several branches of atmospheric sciences, from …

We investigate numerically the influence of the pressure on femtosecond filamentation in air.
We show that femtosecond filamentation occurs at low pressure and compute the features of …

A new regime of the sliding-mode propagation of microwave radiation in plasma
waveguides in atmospheric air is studied both experimentally and theoretically. The …

Due to the intermittent and hazardous nature of lightning impulse, researchers rely on
artificial impulse generators to study it. The Tesla coil is a commonly used device to …

Discharges of different polarities develop in different modes, resulting in different guiding
effects by femtosecond laser filaments. Knowledge of the contribution of laser filaments to …

Lifetime of laser plasma channel is significantly prolonged using femtosecond laser pulse
sequence, which is generated from a chirped pulse amplification laser system with pure …

Lightning is one of the fascinating phenomena exhibiting tremendous natural power. It is
source of awe, curiosity, enticement, inspiration as well as fear. On average, 50 lightning …

Results are presented from a series of experimental and theoretical studies on creating
weakly ionized extended plasma channels in atmospheric air by 248-nm UV laser radiation …

We present experimental studies of filamentation of a femtosecond laser pulse in air at low
pressures. The evolution of the filament has been studied by measuring along the …
