摘要
The acceleration of charged particles in vacuum by chirped laser pulses is influenced by many factors. In this paper, the scaling laws of charged particle acceleration by chirped linearly polarized Gaussian laser pulses are investigated via numerical simulation. It is found how the laser parameters (chirp parameter, laser beam waist, laser pulse duration, and laser field intensity) influence the energy gain of a charged particle. Simple relationships between the outgoing energy and the main parameters of a chirped laser pulse are also obtained.
