Abstract

The paper reports the results of calculations of the generation of twisted photons by relativistic electrons in the laser wave field with linear polarization. It is shown that in this case the probability of radiation of twisted photons obeys the selection rule that n + m is an even number. The radiation of the probability of detecting a twisted photon is numerically investigated depending on various parameters: photon energy, helicity and the cone opening of the twisted photon. In general, the radiation of twisted photons by electrons in the laser wave field with linear polarization is a mixture of twisted photons at the total angular momentum of the photons; however, we have found conditions when generation of twisted photons will be an almost pure source of twisted photons.
线性偏振激光波场中相对论电子辐射的轨道角动量
本文报告了相对论电子在线性偏振激光波场中产生扭曲光子的计算结果。结果表明,在这种情况下,扭曲光子的辐射概率服从 n + m 为偶数的选择规则。根据各种参数:光子能量、螺旋度和扭曲光子的锥开口,对探测到扭曲光子的辐射概率进行了数值研究。一般来说,电子在线性偏振的激光波场中辐射的扭曲光子是光子总角动量下的扭曲光子混合物;但是,我们也发现了产生扭曲光子的条件,即扭曲光子几乎是纯粹的扭曲光子源。
