Numerical simulations of the acceleration of an electron by a pair of phased intersecting Gaussian laser beams and of the electromagnetic emissions by the electrons are carried out. The study is based on solving equations of the relativistic electron dynamic with the corresponding Lorentz force. The electron emissions are calculated with the help of the Lienard–Wiechert potentials, taking into account the retardation of the propagating fields. Differences between the electron acceleration and emissions in intersecting laser beams and in a single Gaussian beam are examined. It is shown that the integral emission energy is maximal for the symmetric trajectory and that the acceleration and emission are competing processes.

进行了一对相交的高斯激光束对电子的加速和电子的电磁发射的数值模拟。该研究基于求解具有相对应的洛伦兹力的相对论电子动力学方程。考虑到传播场的延迟，借助Lienard-Wiechert势计算电子发射。研究了相交激光束和单个高斯光束中电子加速和发射之间的差异。结果表明，对于对称轨迹，积分发射能量最大，而加速度和发射是相互竞争的过程。
