Phase control in high-gradient laser particle accelerators

High gradient acceleration can be achieved in a free-space laser particle accelerator by generating an interference pattern in the laser wave in which electrons move in phase with the laser in regions of constructive interference and out of phase in regions of destructive interference. The desired interference pattern is created by proper design of a holographic grating on the surface of the entrance optic. The approach for designing such a system is described and examples are presented.<
