The wakefield excited by an ultrashort and ultrahigh laser pulse propagating through tenuous plasma can accelerate electrons to extreme high energy . this can be used as a mechanism to design minitype electron accelerator . this thesis is devoted to studying those issues relevant to the wakefield accelerator , namely the laser wakefield accelerator ( lwfa ) , laser wakefield accelerator driven by multiple pulses ( mp - lwfa ) , plasma beat wave accel - erator ( pbwa ) and self - modulated laser wakefield accelerator ( sm - lwfa )
本文的目的是：利用粒子模拟方法，研究和比较激光尾流场加速电子的四种主要方案：短脉冲激光尾流场加速( lwfa ) 、多脉冲激光尾流场加速( mp - lwfa ) 、拍频束尾流场加速( pbwa ) 、自调制激光尾流场加速( sm - lwfa ) 。
