| 摘 要： | 依据非线性强场效应的基本原理,提出了一种四光束捕获电子的方案,旨在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的总概率,实现观测信号的增强。其基本原理是基于电子在强激光光束上的非弹性散射。数值模拟结果表明,捕获后的电子和中心光场的相互作用时间得到延长。 |

| Abstract: | Based on the basic principle of nonlinear strong-field effect induced by the free electron interaction with intense laser fields, a scheme to trap the high-energy electrons by four propagating laser beams has been proposed to improve the total probability of nonlinear process by prolonging the interaction time of free electron and strong field. The mechanism is based upon the electron scattering by intense laser beams. The numerical simulation results show that the interaction time between electrons trapped and central optical field has been prolonged. |
| Keywords: | scattering electron trapping four intense laser beams well shaped formation high-energy electron |
