Quantum electrodynamics in a laser and the electron laser collision

TL;DR

This paper formulates quantum electrodynamics in a laser environment, considering electron-laser interactions exactly and electron-photon interactions perturbatively, to analyze electron-laser collisions and explore gamma-ray laser generation.

Contribution

It introduces a new formulation of QED in a laser, fully accounting for photon coherence in electron-laser collisions, and discusses gamma-ray laser generation possibilities.

Findings

Electron-laser interactions are exactly modeled.

Photon coherence effects are fully incorporated.

Potential for gamma-ray laser generation is discussed.

Abstract

Quantum electrodynamics in a laser is formulated, in which the electron-laser interaction is exactly considered, while the interaction of an electron and a single photon is considered by perturbation. The formulation is applied to the electron-laser collisions. The effect of coherence between photons in the laser is therefore fully considered in these collisions. The possibility of $\gamma-$ray laser generation by use of this kind of collision is discussed.
