提出了一种利用两束线偏振激光脉冲在真空中加速电子的新方法。通过模拟，在实际激光参数下，与单脉冲峰值强度加倍的加速方案相比，能量和空间扩展大大减小，同时在一定的脉冲长度下，平均能量增益可以增加一倍。利用数值模拟，我们的加速方案的最佳制度的分析标准。
A novel electron acceleration approach with two overlapping linearly polarized laser pulses in vacuum is proposed. By our simulation, the energy and space spreads can reduce greatly comparing with the acceleration with only one laser pulse having doubled peak laser intensity for realistic laser parameters and the average energy gain from our scheme can be doubled for certain pulse lengths, at the same time. Using numerical simulation, analytical criteria for optimal regimes of our acceleration scheme is found.
