摘要
为了在实验上增强非线性强场效应的信号强度, 基于电子在强激光束上的非弹性散射,提出一种双光束捕获电子的方案, 目的是通过延长电子和强场相互作用时间来提高非线性过程发生总概率, 实现观测信号的增强。数值模拟结果表明, 捕获后的电子和强激光场的相互作用时间可延长10倍以上。
Abstract
In order to enhance the signal of the weak nonlinear strong-field phenomenon induced by free electron interaction with intense laser fields, a scheme to trap the high-energy electrons by two parallel-propagating laser beams has been proposed. The mechanism is based upon the electron inelastic scattering by intense laser beams, i.e., when the electron passes the first beam with greatly reduced transverse momentum, it will not have enough momentum to pass the second beam and thus be trapped between the two beams.
