Nonlinear Compton scattering of ultrarelativistic electrons traversing high-intensity laser pulses generates hard photons. These photon high-energy tails are considered to be parameters within reach in the forthcoming LUXE and E-320 experiments. We consider the invariant differential cross sections $d\sigma /du$ 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 the initial electron to the 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 $\xi =1,\cdots ,10$. Some supplemental information is provided for the azimuthal final-electron and final-photon distributions and the photon-energy differential cross sections.

非线性康普顿散射中激光偏振对q指数光子尾部的影响

穿越高强度激光脉冲的超相对论电子的非线性康普顿散射产生硬光子。在即将进行的LUXE和E-320实验中，这些光子高能尾部被认为是可以达到的参数。我们考虑不变的微分截面$d\sigma /dü$ 在红外和紫外区域之间，分析激光偏振的影响，并找到 $q$变形的指数形状。（变量$ü$ 是从初始电子到最终光子的光锥动量传递。）将各种持续时间的激光脉冲与单色激光束模型进行比较，该模型揭示了该范围内的激光强度参数 $\xi =\mathrm{1个}，\cdots ，10$。提供了一些关于方位角最终电子和最终光子分布以及光子能量微分截面的补充信息。
