Electromagnetic cascade in high-energy electron, positron, and photon interactions with intense laser pulses
Electromagnetic cascade in high-energy electron, positron, and photon interactions with intense laser pulses
The interaction of high-energy electrons, positrons, and photons with intense laser pulses is studied in head-on collision geometry. It is shown that electrons and/or positrons undergo a cascade-type process involving multiple emissions of photons. These photons can consequently convert into electron-positron pairs. As a result charged particles quickly lose their …
