Abstract
Dielectric laser-driven accelerators (DLAs) can provide high accelerating gradients in the GV/m range due to their higher breakdown thresholds than metals, which opens the way to miniaturize our next-generation particle accelerator facility. However, the electron energy gain is limited by the short interaction length between the laser pulses and the electron bunch for previously reported DLAs. This paper numerically investigates the dual-grating DLAs driven by a pulse-front-tilted (PFT) laser which extends the interaction length and boosts the electrons energy gain. The optical system to generate the PFT laser beam is also studied in detail. By two-dimensional (2D) particle-in-cell simulations we show that such a PFT laser effectively increases the energy gain by more than 100% as compared to that of a normally incident laser beam.
