Analytical theory of coherent radiation and radiation friction in laser-plasma collisions
E. G. Gelfer, A. M. Fedotov, M. P. Malakhov +4
We develop an analytical theory of coherent (scaled quadratically with the number of particles) radiation and coherent radiation friction in a head-on collision of a dense charged…
Coherently enhanced radiation friction in laser-plasma collisions
E. G. Gelfer, A. M. Fedotov, M. P. Malakhov +2
We reconsider the footprints of radiation friction in a head-on collision of a bunch of relativistic charged particles with a laser pulse by demonstrating that forward and backward…
Strong-field ionization in particle-in-cell simulations
A. A. Mironov, E. G. Gelfer, I. I. Tupitsyn +11
The inclusion of the process of multiple ionization of atoms in high-intensity electromagnetic fields into particle-in-cell (PIC) codes applied to the simulation of laser-plasma in…
Coherent radiation of an electron bunch colliding with an intense laser pulse
Evgeny Gelfer, Alexander Fedotov, Ondrej Klimo +1
We study the conditions for coherent radiation of an electron bunch driven by a counterpropagating strong pulsed electromagnetic plane wave. We derive the spectrum of the coherent…
Onset of electron-seeded cascades in generic electromagnetic fields
A. A. Mironov, E. G. Gelfer, A. M. Fedotov
QED cascades in a strong electromagnetic field of optical range and arbitrary configuration are considered. A general expression for short-time dependence of the key electron quant…
Inverse Compton scattering from solid targets irradiated by ultra-short laser pulses in the regime
Jiří Vyskočil, Evgeny Gelfer, Ondřej Klimo
Emission of high energy gamma rays via the non-linear inverse Compton scattering process (ICS) in interactions of ultra-intense laser pulses with thin solid foils is studied using…
Radiation induced acceleration of ions
Evgeny Gelfer, Alexander Fedotov, Stefan Weber
Radiation friction can have a substantial impact on electron dynamics in a transparent target exposed to a strong laser pulse. In particular, by modifying quiver electron motion, i…
Absorption and opacity threshold for a thin foil in a strong circularly polarized laser field
Evgeny Gelfer, Alexander Fedotov, Ondrej Klimo +1
We show that a commonly accepted transparency threshold for a thin foil in a strong circularly polarized normally incident laser pulse needs a refinement. We present a new analytic…
Theory and simulations of radiation friction induced enhancement of laser-driven longitudinal fields
E G Gelfer, A M Fedotov, S Weber
We consider the generation of a quasistatic longitudinal electric field by intense laser pulses propagating in a transparent plasma with radiation friction taken into account. For…
Unusual face of radiation friction: enhancing production of longitudinal plasma waves
E. G. Gelfer, N. V. Elkina, A. M. Fedotov
We study the penetration of ultraintense circularly polarized laser pulses into a thick subcritical plasma layer with accounting for radiation friction. We show that radiation pres…
Gravitational waves generated by laser accelerated relativistic ions
Evgeny Gelfer, Hedvika Kadlecová, Ondřej Klimo +2
The generation of gravitational waves by laser accelerated relativistic ions is investigated. The piston and light sail models of laser plasma acceleration are considered and analy…
Electron dynamics, gamma and electron-positron production by colliding laser pulses
M. Jirka, O. Klimo, S. V. Bulanov +5
The dynamics of an electron bunch irradiated by two focused colliding super-intense laser pulses and the resulting gamma and electron-positron production are studied. Due to attrac…
Optimized multibeam configuration for observation of QED cascades
E. G. Gelfer, A. A. Mironov, A. M. Fedotov +4
QED cascades in intense electromagnetic field can occur if the dynamical quantum parameter of a seed electron, which in Compton units coincides with the electron proper acceler…
Radiation friction vs ponderomotive effect
A. M. Fedotov, N. V. Elkina, E. G. Gelfer +2
The concept of ponderomotive potential is upgraded to a regime in which radiation friction becomes dominant. The radiation friction manifests itself in novel features of long-term…
