Gamma photons and electron-positron pairs from ultra-intense laser-matter interaction: A comparative study of proposed configurations

Popis výsledku v původním jazyce

High-energy γ-photon generation via nonlinear Compton scattering and electron-positron pair creation via the Breit-Wheeler process driven by laser-plasma interaction are modeled, and a number of mechanisms are proposed. Owing to the small cross section, these processes require both an ultra-intense laser field and a relativistic electron bunch. The extreme conditions for such scenarios can be achieved through recent developments in laser technology. Photon emission via nonlinear Thomson and Compton scattering has been observed experimentally. High-energy positron beams generated via a multiphoton process have recently been observed too. This paper reviews the principles of γ-ray emission and e+e- pair creation in the context of laser-plasma interaction. Several proposed experimental setups for γ-ray emission and e+e- pair creation by ultra-intense laser pulses are compared in terms of their efficiency and the quality of the γ-photon and positron beams produced for ultrashort (15 fs) and longer (150 fs) multi-petawatt laser beams.
