Abstract In electron microscopy, detailed insights into nanoscale optical properties of materials are gained by spontaneous inelastic scattering leading to electron-energy loss and cathodoluminescence. Stimulated scattering in the presence of externa

We demonstrate the quantized transfer of photon energy and transverse momentum to a high-coherence electron beam. In an ultrafast transmission electron microscope, a three-dimensional phase modulation of the electron wave function is induced by trans

We demonstrate optical phase contrast in near-field imaging of metallic nanostructures using a new combination of inelastic electron-light scattering with Fresnel-mode Lorentz microscopy.

The generation of high-coherence, ultrashort electron pulses, and their manipulation by intense light fields promises new pathways in the active control of free-electron beams. Harnessing the temporal coherence, a broad range of applications was expl

Ultrafast transmission electron microscopy is a promising laser-pump electron-probe technique, which allows for studying ultrafast dynamics with both high spatial and temporal resolution [1]. Besides, the high spatial and temporal coherence of the pu
