论文摘要
我们观察到垂直于驱动激光极化的平面中高谐波的产生,并表明它们是由自旋轨道相互作用驱动的。使用R-Matrix与时间依赖性理论,我们证明,对于某些初始状态,循环或线性极化的谐波是通过由旋转轨道相互作用控制的原子状态之间的众所周知的选择规则而产生的。最后,我们阐明了观察到的谐波与直觉状态相之间的联系。
We observe the generation of high harmonics in the plane perpendicular to the driving laser polarization and show that these are driven by the spin-orbit interaction. Using R-Matrix with time-dependence theory, we demonstrate that for certain initial states either circularly- or linearly- polarized harmonics arise via well-known selection rules between atomic states controlled by the spin-orbit interaction. Finally, we elucidate the connection between the observed harmonics and the phase of the intial state.
