研究了由两个相同频率的光波在真空中形成的光驻波上电子的高阶非线性非弹性散射。利用半经典能量守恒定律和动量守恒定律，得到了所有非线性阶有效散射的初始条件。由四光子散射过程的经典相对论运动方程的微扰解导出了电子静止坐标系中的稳态散射势。对高阶散射过程中引入的电子速度调制幅度进行了数值计算。提出的非弹性相互作用导致电子能量和纵向动量在驱动光波的更高谐波频率上的周期性调制。
We investigate higher-order nonlinear inelastic scattering of electrons at an optical standing wave formed by two light waves with the same frequencies in vacuum. Initial conditions necessary for efficient scattering are obtained from the semiclassical energy and momentum conservation laws for all nonlinear orders. The stationary scattering potential in the electrons’ rest frame is derived from the perturbative solution of the classical relativistic equation of motion for the four-photon scattering process. The amplitude of the electron velocity modulation introduced during higher-order scattering processes is calculated numerically. The proposed inelastic interaction leads to a periodic modulation of the electrons’ energy and longitudinal momentum at a higher harmonic frequency of the driving light waves.
