Observation of terahertz coherent edge radiation amplified by infrared free-electron laser oscillations

open access: yesScientific Reports, 2021
A coupling device, which can extract coherent edge radiation (CER) from an optical cavity for a free-electron laser (FEL) without damaging the FEL due to diffraction loss, was developed at Nihon University.

Manipulating Twisted Electron Beams [PDF]

open access: yesPhysical Review Letters, 2017
A theoretical description of vortex electrons interacting with electric and magnetic fields is presented, based on Lorentz transformations. The general dynamical equations of motion of a twisted electron with intrinsic orbital angular momentum in an external field is derived.
