Description
The acceleration gradient of a solid-state accelerator is limited by the damage of the acceleration field on an accelerator structure. A dielectric, which is widely used for high-power lasers, is therefore the choice of material for an accelerator operating at the optical frequencies. Owing to the much shorter drive wavelength, a dielectric laser accelerator (DLA) built upon a photonic chip could produce nano-electron bunches useful for studying attosecond science or generating electron superradiance in the EUV and soft x-ray spectrum. We show in this presentation that, in the low-current limit, a DLA-driven photonic chip can generate laser-like radiation from a single electron and a train of single electrons; where, with ~fC bunch charge, DLA-driven coherent undulator radiation is the brightest photon source on Earth when the brilliance of radiation per beam power is considered.
