Abstract

Quantum effects in spontaneous and stimulated Compton laser-beam interactions are considered in the frame of the Klein–Gordon theory. We derive a quantum kinetic equation to describe the laser cooling of electron beams. Nonlinear theory of coherent π-pulse generation in the quantum X-ray Compton FEL is presented. A scheme of coherent stimulated annihilation of electron-positron pairs and stimulated emission of γ-ray photons is proposed.
