The fundamental limit of free-electron—light coupling is an important question relevant to frontier studies to reach the strong coupling regime, which is crucial for applications such as free-electron based photon sources, quantum sensing and quantum computing using free electrons. This study rigoro...

We used auto-ponderomotive potentials to guide electrons with kinetic energies of up to 9.5keV. This makes this type of electron beam manipulation also interesting for electron microscopes. The demonstration at higher energies than before paves the way for electron beam splitters and resonators at e...
