Generation of high-flux vortex $ \gamma $-ray pulses is investigated in the interaction of ultraintense Bessel–Bessel laser bullets colliding head-on with ultrarelativistic electron bunches in the quantum radiation-dominated regime. In the simulations, a semiclassical Monte–Carlo method is used, based on the radiation probabilities in the local constant field approximation, to describe the electron motion and emission of radiation. Characteristics of the driving laser pulse (orbital angular momentum and nondiffracting spatial and temporal structures) are transferred to the emitted $ \gamma $ rays by nonlinear Compton scattering.

超相对论电子散射激光子弹产生的涡旋γ射线

在量子辐射主导的状态下，在超强贝塞尔-贝塞尔激光子弹与超相对论电子束的碰撞中研究了高通量涡旋\ \伽马射线射线脉冲的产生。在模拟中，基于局部恒定场近似中的辐射概率，使用了半经典的蒙特卡洛方法来描述电子的运动和辐射的发射。通过非线性康普顿散射，驱动激光脉冲的特性（轨道角动量以及非衍射的时空结构）被转移到发射的γ射线中。
