WebAbstract. We demonstrate focused emission of visible and near-infrared Smith-Purcell radiation by a free-electron-driven metasurface lens emitter. Our findings pave the way for free-electron light sources focusing at wavelengths lacking efficient optics. View More... WebThis thesis investigates the properties of coherent Smith-Purcell radiation (cSPr) at femtosecond-scale in the case of electrons bunches in the ultrarelativistic regimes. Of particular interest is the use of cSPR as a diagnostic tool to determine the longitudinal time profiles of such bunches, the
