脉冲强laser场中的双光子康普顿过程

Two-photon Compton process in pulsed intense laser fields

D. Seipt, B. Kampfer

摘要:

基于Furry图像中的强场QED,利用Dirac-Volkov传播子导出了脉冲强激光场中双光子Compton过程的微分发射几率的一个简洁表达式。讨论了实中间态和虚中间态之间的关系,强调了有限激光脉冲对壳层贡献的自然正则化。包容性的双光子光谱是两个数量级强于预期的微扰估计。

英文摘要:

Based on strong-field QED in the Furry picture we use the Dirac-Volkov propagator to derive a compact expression for the differential emission probability of the two-photon Compton process in a pulsed intense laser field. The relation of real and virtual intermediate states is discussed, and the natural regularization of the on-shell contributions due to the finite laser pulse is highlighted. The inclusive two-photon spectrum is two orders of magnitude stronger than expected from a perturbative estimate.
