摘要

建立了超强短圆偏振激光脉冲聚焦束腰激光团簇等离子体产生同步辐射的解析模型。相对论性电子围绕星团的电离核心旋转，旋转半径小于激光波长，导致在激光波矢量的横向方向上产生强烈的同步辐射。确定了星团等离子体和激光脉冲的参数，在此参数下，由于星团壳层电子轨迹的曲率半径小，同步辐射的强度超过了电子通量在纵向(沿波矢量)方向上的电子辐射强度。

Synchrotron radiation from a cluster plasma in a circularly polarised laser field

An analytical model is developed for the generation of synchrotron radiation from a laser cluster plasma in the focal waist of an ultra-intense short circularly polarised laser pulse. The rotation of relativistic electrons around the ionised core of the cluster with a radius of rotation smaller than the laser wavelength leads to intense synchrotron radiation in the direction transverse to the laser wave vector. The parameters of the cluster plasma and laser pulse are determined at which, due to the small radius of curvature of the electron trajectory of the cluster shell, the intensity of synchrotron radiation exceeds the intensity of betatron radiation of the electron flux in the longitudinal (along the wave vector) direction.
