Effect of laser polarization on quantum electrodynamical cascading
Development of quantum electrodynamical (QED) cascades in a standing electromagnetic wave for circular and linear polarizations is simulated numerically with a 3D PIC-MC code. It is demonstrated that
Electron self-injection in multidimensional relativistic-plasma wake fields.
The model predicts the condition for electron trapping and the trapping cross section in terms of the bubble radius and the bubble velocity and is in a good agreement with results of 3D particle-in-cell simulations.
Laser field absorption in self-generated electron-positron pair plasma.
Recently, much attention has been attracted to the problem of limitations on the attainable intensity of high power lasers [A. M. Fedotov et al., Phys. Rev. Lett. 105, 080402 (2010)]. The laser
QED cascades induced by circularly polarized laser fields
The results of Monte-Carlo simulations of electron-positron-photon cascades initiated by slow electrons in circularly polarized fields of ultra-high strength are presented and discussed. Our results
Energy partition, γ-ray emission, and radiation reaction in the near-quantum electrodynamical regime of laser-plasma interaction
When extremely intense lasers (I ≥ 1022 W/cm2) interact with plasmas, a significant fraction of the pulse energy is converted into photon emission in the multi-MeV energy range. This emission results
Laser field absorption in self-generated electron-positron pair plasma.
The numerical model for a self-consistent study of electron-positron pair plasma dynamics is developed and it is shown that the absorption becomes important for a not extremely high laser intensity I ∼ 10(24)  W/cm(2) achievable in the near future.
Fast electron generation using PW-class PEARL facility
We use a PW-class PEARL facility to study fast electron beam generation during high intensity laser pulse interaction with a supersonic gas jet. We show that electron beams with several hundreds of
Gamma-ray generation in ultrahigh-intensity laser-foil interactions
Incoherent photon emission by ultrarelativistic electrons in the normal incidence of a laser pulse on a foil is investigated by means of three-dimensional numerical simulations in the range of
Carrier-envelope phase effects in plasma-based electron acceleration with few-cycle laser pulses.
It is shown that for few-cycle laser pulses the cavity shape becomes asymmetric and depends strongly on the carrier-envelope phase, and the degree of plasma cavity asymmetry as a function of the laser-plasma parameters is calculated.
