本文通过数值和解析方法分析了对称强激光脉冲和弱激光脉冲的前后结合所形成的混合激光激发的尾场的参数对尾场势的影响。讨论了在弱脉冲的位置有所改动的条件下，尾场最大和最小势随各激光脉冲参数变化的敏感度。

Electron acceleration in the first cycle of a plasma wakefield driven by combined two laser pulses with different intensity and pulse duration is investigated analytically and numerically. It is found that the combined laser pulses can e?ciently modify the plasma wakefield potential and phase portrait of the electron dynamics. The optimum combination of two laser pulses to maximize the net energy gain of the accelerated electrons is discussed.
