TL;DR: In this article, the optical field imprints a sinusoidal phase modulation on the electron wave function, which manifests in a comb of photon sidebands in the kinetic energy distribution and enables photon-induced near-field electron microscopy (PINEM).
Generation and attosecond shaping of high coherence free-electron beams for ultrafast TEM
Armin Feist,Katharina E. Priebe,Christopher Rathje,Christopher Rathje,Nora Bach,Nara Rubiano da Silva,Thomas Danz,Marcel Möller,Till Domröse,Thomas Rittmann,Sergey V. Yalunin,Thorsten Hohage,Murat Sivis,Sascha Schäfer,Sascha Schäfer,Claus Ropers +15 more
TL;DR: In this paper, the generation and optical control of ultrashort high-coherence electron pulses is demonstrated, where the free-electron quantum state is phase modulated in the longitudinal and transverse dimensions.
Attosecond electron microscopy using free-electron homodyne detection
John Gaida,Hugo Lourenço-Martins,Murat Sivis,Thomas Rittmann,Armin Feist,F. J. G. de Abajo,Claus Ropers +6 more
TL;DR: Researchers develop attosecond electron microscopy in a TEM, achieving 54 attosecond temporal and few-nanometer spatial resolution, using free-electron homodyne detection to measure the optical near-field of a plasmonic nanoprism.
