Elastic quantum coupling between free electrons and photons

The quantum coupling between free electrons and photons enables the application of quantum optics techniques in electron microscopy. For example, the phase of the electron wave function can be manipulated by passing the electron through an intense laser field. We develop here a q...

Photon‐Recycling Dielectric Laser Accelerator

ABSTRACT We propose a photon‐recycling dielectric laser accelerator (DLA) system based on silicon‐on‐insulator platform. Our DLA system employs transverse‐magnetic optical mode as the primary energy source, modulated and injected into the electron‐light interaction region for lon...
