标题： Optical control of resonant Auger processes

摘要： 我们理论证明，在几个飞秒内其衰减过程中，可以通过强光场有效地操控核心激发态的种群。 我们关注氖中$1s^{-1}3p$共振激发，其中$1s^{-1}3p$和$1s^{-1}3s$核心激发态被光场耦合。 通过分析俄歇电子谱，我们观察到由光耦合引起的内壳层种群转移。 我们还表明，俄歇电子的角各向异性被印在由光致密连续态引起的多峰结构中，即边带。 显示英文摘要

摘要： We theoretically show that core-excited state populations can be efficiently manipulated with strong optical fields during their decay, which takes place in a few femtoseconds. We focus on the $1s^{-1}3p$ resonant excitation in neon, where the $1s^{-1}3p$ and $1s^{-1}3s$ core-excited states are coupled by an optical field. By analyzing the Auger electron spectrum we observe the inner-shell population transfer induced by the optical coupling. We also show that the angular anisotropy of the Auger electron is imprinted in the multipeak structure induced by the optical-dressed continuum, namely sidebands.
