Description
The acceleration gradient of a solid-state accelerator is limited by the damage field to the structure material. A dielectric is therefore the choice of material for an accelerator operating at the optical frequencies. A dielectric laser accelerator has the potential of stable high-gradient electron acceleration over a long distance. Owing to the much shorter drive wavelength, a dielectric laser accelerator could also produce very short electron bunches useful for studying attosecond science or generating EUV superradiance. The inverse process of particle acceleration is particle radiation. In this presentation, we will show various mechanisms to generate laser-like radiation from a beam-driven dielectric structure. The coherent radiation by itself is useful for applications. However, we will show how we optimize the design of a dielectric accelerator structure by maximizing the coherent radiation from the structure.
