When high-intensity laser interaction with matter enters the regime of dominated radiation
reaction, the radiation losses open the way for producing short pulse high-power γ-ray …

This paper studies the interaction of laser-driven γ photons and high-energy charged
particles with high-Z targets through Monte Carlo simulations. The interacting particles are …

We use quantum electrodynamics (QED) particle-in-cell simulations to investigate and
compare the generation of dense electron-positron plasmas and intense γ-ray bursts in the …

This paper presents experimental scalings of the electrons and positrons produced by
intense laser-target interactions at relativistic laser intensities (10 18–10 20 W cm− 2). The …

Gamma-ray flash in the interaction of a tightly focused single-cycle ultra-intense laser pulse
with a solid target Page 1 J. Plasma Phys. (2022), vol. 88, 905880104 © The Author(s), 2022 …

Collimation of positrons produced by laser-solid interactions has been observed using an
externally applied axial magnetic field. The collimation leads to a narrow divergence …

The relaxed state of a magnetized relativistic hot plasma composed of inertial electrons and
positrons having different relativistic temperatures and a fraction of static positive ions is …

We report a target design which produced a substantial gain in relativistic electron-positron
pair production using high-intensity lasers and targets with large-scale micro-structures on …

Dynamical properties of nonlinear ion-acoustic waves (IAWs) in multi-pair plasmas (MPPs)
constituting adiabatic ion fluids of positive and negative charges, and q-nonextensive …

We report the observation of charge-neutral MeV electron–positron beams from
magnetically collimated laser-driven pair-production experiments. Relativistic pairs of …
