Abstract

Providing the most detailed views of atomic-scale structure and composition, Transmission Electron Microscopy (TEM) serves as an indispensable tool for structural biology and materials science. Optical excitations in electron microscopy are accessible through spontaneous inelastic scattering of electrons, analyzed in electron-energy loss and cathodoluminescence spectroscopy [1]. The stimulated variants of the underlying scattering processes become accessible through optical illumination of the sample [2], leading to quantum-coherent superpositions of free-electron momentum states [3].
