通过自相互作用控制的电子动力学
Electron dynamics controlled via self-interaction
摘要：
电子在强激光场中的动力学可以通过辐射反应而显著改变。这通常会导致强烈的阻尼运动，电子失去了大部分的初始能量。本文证明了双色激光脉冲中的电子动力学可以通过辐射反作用力与洛伦兹力的相互作用而被较小的辐射反作用力间接控制。通过改变双色激光场的两个频率分量之间的相对相位，可以以受控的方式偏转与激光脉冲正面碰撞的超相对论性电子聚束，偏转角与初始电子能量无关。预测的效果是可观察到的激光功率和强度接近目前最先进的拍瓦激光系统。
英文摘要：
The dynamics of an electron in a strong laser field can be significantly altered by radiation reaction. This usually results in a strongly damped motion, with the electron losing a large fraction of its initial energy. Here we show that the electron dynamics in a bichromatic laser pulse can be indirectly controlled by a comparatively small radiation reaction force through its interplay with the Lorentz force. By changing the relative phase between the two frequency components of the bichromatic laser field, an ultrarelativistic electron bunch colliding head-on with the laser pulse can be deflected in a controlled way, with the deflection angle being independent of the initial electron energy. The effect is predicted to be observable with laser powers and intensities close to those of current state-of-the-art petawatt laser systems.
