The possibility of enhancing the energy gain in vacuum electron acceleration by Airy beams is examined. The characteristics of transverse acceleration and non-diffraction of Airy beam can lead to the formation of a long "asymmetric field channel" along the propagation axis, where the intense asymmetric field can accelerate the injected electron to higher energy. Meanwhile, the injection energy of electron plays an important role in determining the final energy gain.
研究了利用艾里光束提高真空电子加速中能量增益的可能性。艾里光束的横向加速和无衍射特性可导致沿传播轴形成一个长的“非对称场通道”，其中强烈的非对称场可将注入的电子加速到更高能量。同时，电子的注入能量在确定最终能量增益方面起着重要作用。
