Large-scale, relativistic particle-in-cell simulations with quantum electrodynamics (QED) models show that high energy (1$<E_\gamma\lesssim$ 75 MeV) QED photon jets with a flux of $10^{12}$ sr$^{-1}$ can be created with present-day lasers and planar, unstructured targets. This process involves a self-forming channel in the target in response to a laser pulse focused tightly ($f$ number unity) onto the target surface. We show the self-formation of a channel to be robust to experimentally… Expand

Radiation-reaction trapping of electrons in extreme laser fields.
TLDR
A radiation-reaction trapping (RRT) of electrons is revealed in the near-QED regime of laser-plasma interaction and the threshold of laser field amplitude for RRT is approximately the cubic root of laser wavelength over classical electron radius. Expand
Photon beams for radiosurgery produced by laser Compton backscattering from relativistic electrons.
TLDR
The Monte Carlo study has shown that radiosurgery with photon beams of energies in mega-electron-volt energy range enables precise destruction of deeply lying millimetre-sized targets with minimal effects on intervening structures, and it is hoped that radiosugery with lower energy photon beams could be more precise and less expensive.
