Using numerical simulation, we have studied in detail vacuum electron acceleration induced by an Airy beam. The phase of the field varies slowly, and the intensity of the field is independent of the decaying parameter of the beam in the asymmetric field channel [(AFC) Opt. Express 18, 7300 (2010)] formed by the Airy beam. Results show that an electron entering into the AFC may be captured and gain high energy. Meanwhile, the decaying parameter, injection energy, and injection angle of the electron play important roles in the electron energy gain.
我们通过数值模拟详细研究了由艾里光束引起的真空电子加速。在由艾里光束形成的非对称场通道 [(AFC) Opt. Express 18, 7300 (2010)] 中，场的相位变化缓慢，并且场的强度与光束的衰减参数无关。结果表明，进入 AFC 的电子可能会被捕获并获得高能。同时，电子的衰减参数、注入能量和注入角度在电子能量增益中起着重要作用。
