Three-dimensional ``particle in cell'' simulations show that a quasistatic magnetic field can be generated plasma irradiated by linearly polarized Laguerre-Gauss beam with nonzero orbital angular momentum (OAM). Perturbative analysis of the electron dynamics low intensity limit and detailed numerical predict laser to electrons OAM transfer. Plasma gain velocity thanks dephasing process induced combined action ponderomotive force induced--radial oscillation. Similar ``direct acceleration,''...
This work presents a general concept of an intense laser-driven source strong electromagnetic waves, which can be used for obtaining powerful terahertz radiation with controlled polarization. It is shown that the irradiation solid target surface by short relativistic laser pulses at small angles provides excitation compact discharge current pulses, propagating in certain direction. For elliptical targets, this emits elliptically polarized given frequency ellipticity and spectra defined...
Abstract The effect of energy transfer by laser-accelerated fast electrons on thermonuclear gain a shock-ignited ICF target at different powers and durations the high-intensity part laser pulse (spike) responsible for igniting shock wave generation has been investigated basis hydro-kinetic numerical simulations. key result these studies is that fast-electron able to provide great contribution pressure maintain high with significant decrease in pulse. Calculations were performed 2nd harmonic...
The problem of light waves interaction with charged particles becomes more and complex starting the case plane waves, where analytical solution is well known, to natural, though complicated situations which include focused or structured laser beams. Internal structure may introduce a new degree freedom qualitatively change dynamics interacting particles. For certain conditions, namely for dilute plasma, description single-particle in beams first step serve as good approximation on way...

A structure of a laser pulse may significantly influence the dynamics interacting particles. In case dilute plasma particle be considered in single approximation. this paper problem angular momentum gain focused structured is for some certain cases, including radial and azimuthal polarizations, frameworks theoretical model, presented [E. Dmitriev Ph. Korneev, 'Angular by electrons under action intense light', Physical Review A, vol. 110, p. 013514, (2024)], which includes solving Maxwell's...
