提出了一种利用激光有质动力沿靶表面沿着加速产生高质量准单能阿秒电子束团的方案。二维和三维粒子模拟表明，电子能量对靶密度的依赖性很弱。一个简单的分析模型表明，电子能量与激光场的振幅成线性关系，与模拟结果吻合得很好。该方案产生的电子束团适用于相干X射线辐射、射线照相和加速器注入器等应用。
A scheme is proposed to produce high-quality quasi-monoenergetic attosecond electron bunches based on laser ponderomotive-force acceleration along the surface of wire or slice targets. Two- and three-dimensional particle-in-cell simulations demonstrate that the electron energy depends weakly on the target density. A simple analytical model shows that the electron energy scales linearly with the laser field amplitude, in good agreement with the simulation results. Electron bunches produced by this scheme are suitable for applications such as coherent x-ray radiation, radiography, and injectors in accelerators, etc.
