Electron-Photon Interaction

  • Helmut Schwarz
Conference paper


A short survey of recent experimental and theoretical results on the Kapitza-Dirac Effect (the reflection of electrons from a standing light wave) will be given. Higher order calculations show that the effect under certain conditions may disappear while increasing the intensity. — In the second half, results on the optical modulation of an electron beam will be presented. The modulation experiment is performed by an electron beam passing through a thin crystal modulated by laser light which shines through it. The light is then reproduced when the electron beam strikes a nonluminescent target. Further experimental and theoretical results, especially on the monochromaticity requirements for the electron beam, and the quantum mechanical nature of the effect, are reported.
