论文摘要
横穿高强度激光脉冲的超偏见电子的非线性康普顿散射也会产生硬光子。这些光子高能尾部被考虑在即将到来的实验豪华和E-320的实验中进行参数。我们考虑IR和UV区域之间的不变差分截面$dσ/ du $，并分析激光极化的影响并找到Q指数的指数形状。 （可变$ u $是从初始电子到最终光子的轻曲动量转移。）将各个持续时间的光学激光脉冲与单色激光束模型进行比较，该脉冲可以在$ξ= 1 \ cdots 10 $的范围内发现激光强度参数。为方位角最终电子/光子分布和光子能量差异截面提供了一些补充信息。
Non-linear Compton scattering of ultra-relativistic electrons traversing high-intensity laser pulses generates also hard photons. These photon high-energy tails are considered for parameters in reach at the forthcoming experiments LUXE and E-320. We consider the invariant differential cross sections $d σ/ du$ between the IR and UV regions and analyze the impact of the laser polarization and find q-deformed exponential shapes. (The variable $u$ is the light-cone momentum-transfer from initial electron to final photon.) Optical laser pulses of various durations are compared with the monochromatic laser beam model which uncovers the laser intensity parameter in the range $ξ= 1 \cdots 10$. Some supplementary information is provided for the azimuthal final-electron/photon distributions and the photon energy-differential cross sections.
