标题： Thomson and Compton scattering with an intense laser pulse

摘要： 我们的论文涉及强激光辐射与自由电子的散射，重点研究非线性康普顿散射和非线性汤姆逊散射之间的关系。 分析针对由理想脉冲建模的激光场进行，该脉冲具有有限持续时间、固定传播方向，并在垂直于传播方向的平面内无限延伸。 我们推导了发射辐射的量子谱分布和角度分布的经典极限，对于激光脉冲的任意偏振情况。 我们还直接在经典电动力学框架中重新推导了这一结果，同时得到了具有明确偏振的发射辐射分布。 这些结果在脉冲线性偏振且与初始电子动量正交的特殊情况下，与Krafft等人[Phys. Rev. E 72, 056502 (2005)]建立的结果一致。 讨论并图示了经典结果与量子结果之间差异可见的条件。 显示英文摘要

摘要： Our paper concerns the scattering of intense laser radiation on free electrons and it is focused on the relation between nonlinear Compton and nonlinear Thomson scattering. The analysis is performed for a laser field modeled by an ideal pulse with a finite duration, a fixed direction of propagation and indefinitely extended in the plane perpendicular to it. We derive the classical limit of the quantum spectral and angular distribution of the emitted radiation, for an arbitrary polarization of the laser pulse. We also rederive our result directly, in the framework of classical electrodynamics, obtaining, at the same time, the distribution for the emitted radiation with a well defined polarization. The results reduce to those established by Krafft et al. [Phys. Rev. E 72, 056502 (2005)] in the particular case of linear polarization of the pulse, orthogonal to the initial electron momentum. Conditions in which the differences between classical and quantum results are visible are discussed and illustrated by graphs.
