论文摘要
我们提出了一种使用几个周期和紧密聚焦的径向极化激光脉冲产生飞秒，相对论和高充电电子束的方法。在此方案中，入射激光脉冲反映了一个过度密度的血浆，该血浆将电子注入反射脉冲中。粒子中的模拟表明，等离子体理想地注入电子，从而导致与以前的方法相比，加速电子束的电荷和能量急剧增加。该方法可用于使用与当前KHz激光系统相对应的逼真的激光参数来生成具有1-10 MEV范围内能量的飞秒PC束。
We propose a method to generate femtosecond, relativistic and high-charge electron bunches using few-cycle and tightly focused radially polarized laser pulses. In this scheme, the incident laser pulse reflects off an overdense plasma that injects electrons into the reflected pulse. Particle-In-Cell simulations show that the plasma injects electrons ideally, resulting in a dramatic increase of charge and energy of the accelerated electron bunch in comparison to previous methods. This method can be used to generate femtosecond pC bunches with energies in the 1-10 MeV range using realistic laser parameters corresponding to current kHz laser systems.
