摘要

本文报道了平面波激光脉冲在正碰撞几何中的非线性区域对电子的康普顿散射过程。利用广义Filon方法，对快速振荡积分进行数值计算，确定了该过程在Furry表示中的矩阵元素。作为激光脉冲振幅、持续时间、偏振和包络形状的函数，分析了散射光子的光谱角分布、角分布和光谱分布的行为。得到了圆极化脉冲特殊包络形状后向散射谱的解析表达式。

Calculation of Spectral and Angular Characteristics of Nonlinear Compton Scattering of a Laser Pulse

We report an investigation of the process of Compton scattering of a plane-wave laser pulse on an electron in the nonlinear regime in the head-on collision geometry. Use is made of the generalized Filon method to calculate numerically the rapidly oscillating integrals that determine the matrix element of the process in the Furry representation. The behavior of the spectral-angular, angular, and spectral distributions of a scattered photon is analyzed as a function of the laser pulse amplitude, duration, polarization, and envelope shape. A new analytical expression for the backscattering spectrum is obtained for a special envelope shape of a circularly polarized pulse.
