在低强度的入射光子束的激光-电子散射的背景下，我们提出了一个讨论的领先的多光子反应，双光子吸收的自由电子在一个类康普顿过程。在量子电动力学中计算了双光子角分布，并与现有的经典和半经典汤姆逊极限计算进行了比较。我们认为，对于入射的线偏振光，所有这些计算在这个极限内是一致的。此外，本方法还允许我们研究重合光子对的量子力学关联的可能效应，即。e.二阶相干度。
Within the context of laser-electron scattering for low intensities of the incoming photon beam, we present a discussion of the leading multiphoton reaction, two-photon absorption by a free electron in a Compton-like process. The two-photon angular distribution is calculated in quantum electrodynamics and compared with existing classical and semiclassical calculations in the Thomson limit. We 6nd that for incident linearly polarized beams all such calculations agree in this limit. Furthermore, the present approach allows us to study the possible effect of the quantum-mechanical correlation of pairs of coin-cident photons, i. e. , the degree of second-order coherence.
