Abstract
In order to study the kinetic energy of the accelerated positrons in the wakefield of different laser pulses, by means of numerical simulation, the kinetic energy was obtained in the wakefiled of sine, flat-top and Gaussian asymmetric laser pulses. Simulation results show the energy driven by asymmetric sine pulses is higher than those driven by flat-top and Gaussian laser pulses.
