Abstract:Exact solutions describing the nonlinear electrodynamics of a thin double layer foil are presented. These solutions correspond to a broad range of problems of interest for the interaction of high intensity laser pulses with overdense plasmas such as frequency upshifting, high order harmonic generation and high energy ion acceleration.
“…Theoretical analysis of the target off-axis displacement effects has been carried within the framework of the linearized model equations (24)(25)(26). In order to take into account the nonlinear and kinetic effects, the target deformation and instability we have conducted a series of 2D-PIC simulations using the two-dimensional version of relativistic electromagnetic code REMP [44].…”

In the ion acceleration by radiation pressure a transverse inhomogeneity of the electromagnetic pulse results in the displacement of the irradiated target in the off-axis direction limiting achievable ion energy. This effect is described analytically within the framework of the thin foil target model and with the particle-in-cell simulations showing that the maximum energy of accelerated ions decreases while the displacement from the axis of the target initial position increases. The results obtained can be applied for optimization of the ion acceleration by the laser radiation pressure with the mass limited targets.

“…The 1D electrodynamics model, where the role of a point charge is played by an infinitely thin foil [55][56][57], has been extensively used in studying the problem of relativistic thin plasma layer transparency, particularly for the purposes of the laser pulse shaping [55] (see also the experimental paper [58]), in high order harmonics generation [59][60][61], in laser ion acceleration [61], in the analysis of the radiation friction effects [62] and in the generation of coherent extremely high intensity x-ray pulses by relativistic mirrors [3,47].…”

Relativistic flying mirrors in plasmas are realized as thin dense electron (or electron-ion) layers accelerated by high-intensity electromagnetic waves to velocities close to the speed of light in vacuum. The reflection of an electromagnetic wave from the relativistic mirror results in its energy and frequency changing. In a counter-propagation configuration, the frequency of the reflected wave is multiplied by the factor proportional to the Lorentz factor squared. This scientific area promises the development of sources of ultrashort X-ray pulses in the attosecond range. The expected intensity will reach the level at which the effects predicted by nonlinear quantum electrodynamics start to play a key role.
Magnetic reconnection driven by laser plasma interactions attracts great interests in the recent decades. Motivated by the rapid development of the laser technology, the ultra strong magnetic field generated by the laser-plasma accelerated electrons provides unique environment to investigate the relativistic magnetic field annihilation and reconnection. It opens a new way for understanding relativistic regimes of fast magnetic field dissipation particularly in space plasmas, where the large scale magnetic field energy is converted to the energy of the nonthermal charged particles. Here we review the recent results in relativistic magnetic reconnection based on the laser and collisionless plasma interactions. The basic mechanism and the theoretical model are discussed. Several proposed experimental setups for relativistic reconnection research are presented.
