Radiation reaction effects in the interaction of an electron and a strong laser field are investigated in the realm of quantum electrodynamics. We identify the quantum radiation reaction with the multiple photon recoils experienced by the laser-driven electron due to consecutive incoherent photon emissions. After determining a quantum radiation dominated regime, we demonstrate how in this regime quantum signatures of the radiation reaction strongly affect multiphoton Compton scattering spectra and that they could be measurable in principle with presently available laser technology.
在量子电动力学的范畴内，研究了电子与强激光场相互作用中的辐射反应效应。我们将量子辐射反应与激光驱动电子因连续非相干光子发射而经历的多次光子反冲联系起来。在确定了一个量子辐射主导的区域后，我们展示了在这个区域中，辐射反应的量子特征如何强烈影响多光子康普顿散射谱，并且原则上可以用目前可用的激光技术来测量。
