We discuss generation of energetic photons in strong laser field at intensities above 10^23 W/cm^2. First we discuss production of electron-positron-gamma-quanta plasma at QED cascading. QED or electromagnetic cascades are one of the basic phenomena of high-field physics. QED cascades can efficiently convert laser radiation into gamma-quanta. The various methods and schemes to control of the...

The quantum vacuum, polarized by a classical electromagnetic field, behaves as an active medium. Its absorptive and dispersive properties are studied in the presence of a high-intensity circularly polarized laser wave. The outcomes of this investigation reveal that, in the region relatively close to the threshold of the two-photon reaction, the birefringence and dichroism of the vacuum can...

Non-linear Compton scattering in ultra-short intense laser pulses is discussed. The focus is on angular and azimuthal distributions of the emitted photon in intense single-cycle and few-cycle laser pulses. Asymmetries of the azimuthal distributions are predicted for both
linear and circular polarization. For linear polarization, the dominant direction of the emission changes from a...

Motivated by the ever-increasing interest in simulating the intense irradiation of plasmas by combining the scales of classical plasma physics and strong-field QED processes, we present the results of two studies into common approximations. First, we derived polarised non-linear Compton scattering and pair-creation rates in a constant crossed field and studied their inclusion in simulations,...
