Abstract: Systems and methods for generating longitudinally modulated (micro-bunched) electron bunches and for generating coherent radiation by the emission from relativistic electrons with a density that is longitudinally modulated (micro-bunched) with a spatial dimension that is significantly below the wavelength of the emitted radiation. The light source includes a high-brightness relativistic electron beam that interacts in a magnetic structure (linear or helical undulator or wiggler) or an electromagnetic structure with a pulse of high-power electro-magnetic wave (modulation laser pulse). The interaction leads to a large energy-modulation of the electron bunch which is transformed into a spatial modulation by an energy-dispersive element that can be the same undulator.
