The electron, positron, and photon acceleration in the first cycle of a laser-driven wakefield is investigated. Separatrices between different types of the particle motion (trapped, reflected by the wakefield and ponderomotive potential, and transient) are demonstrated. The ponderomotive acceleration of electrons can be largely compensated by the wakefield action, in contrast to positrons and positively charged mesons. The electron bunch energy spectrum is analyzed. The maximum upshift of an electromagnetic wave frequency during reflection from the wakefield is obtained.
研究了激光驱动尾波场第一个周期中的电子、正电子和光子加速。展示了不同类型粒子运动（被俘获、被尾波场和有质动力势反射以及瞬态）之间的分界线。与正电子和带正电介子不同，电子的有质动力加速可在很大程度上被尾波场作用所补偿。分析了电子束能谱。获得了电磁波从尾波场反射时频率的最大上移。
