| 摘 要： | 为了研究激光电磁场对真空中电子的作用,从洛伦兹方程出发,得出了电子运动轨迹,实现了激光场对电子的加速。继而由运动电子产生的流密度,得到了电子的辐射能量谱,分析了相对论电子的辐射特点。结果表明,高斯激光场对真空中电子有很好的加速效果,最大轴向速度可达0.9c。

| Abstract: | In order to study the effect of the laser electromagnetic field on the electron in vacuum，based on the Lorentz equation，the motion track of electrons was simulated，and the electrons were accelerated in the laser electromagnetic field. Then the radiant energy spectrum was obtained according to the flux density generated by the motive electron. Finally the radiant characteristics of the relativistic electrons were analyzed. It is shown that Gaussian laser electromagnetic field has beneficial effect on vacuum electron acceleration，and its maximum speed along the optical axis is up to 0.9c. |
