A technique of focusing the heating radiation was investigated, which makes it possible to produce an extended (under laboratory conditions, up to 1 m and over) plasma column and enables an easy output of VUV radiation. A plane solid-state target in

The plasma formed by the breakdown of gases (argon was used in the experiments, whereas argon and helium were considered in the calculations) at atmospheric pressure in light beams was studied experimentally and modelled numerically. The field amplit

Numerical simulation is used to investigate the dynamics of formation of a helium plasma in Bessel beams, shaped by an axicon and a phase converter from a laser radiation pulse with Gaussian temporal and radial intensity profiles. The beam intensitie

An investigation was made of the possibility of conversion of high-power laser beams into hollow Bessel beams with the first maximum in the radial field distribution in the form of a ring and a slight variation of the field in the direction of propag

We report two variations on plasma channel generation using the propagation of intense Bessel beams. In the first experiment, the propagation of a high intensity Bessel beam in neutral gas is observed to give rise to resonantly enhanced plasma channe
