论文摘要
在独立的粒子近似和三阶扰动理论中研究了Biharmonic($ω+3Ω$)的总电离速率。特别关注双向光场的极化如何影响总率。分析了线性和圆形极化光束以及固定和反射椭圆极化的光束的双旋转电离速率的比率,以及它们如何依赖于光束参数,例如光子频率或$ω$和3Ω$ $3Ω$光束之间的相位。我们表明,Biharmonic电离幅度的干扰决定了特定光束极化在另一个方面的优势,并且可以通过适当的光束参数选择来控制它。此外,我们展示了霓虹灯$ l $ shell电子电离的发现。
The total ionization rate of biharmonic ($ω+ 3ω$) ionization is studied within the independent particle approximation and the third order perturbation theory. Particular attention is paid to how the polarization of the biharmonic light field affects the total rate. The ratios of the biharmonic ionization rates for linearly and circularly polarized beams as well as for corotating and counterrotating elliptically polarized beams are analyzed, and how they depend on the beam parameters, such as photon frequency or phase between $ω$ and $3ω$ light beams. We show that the interference of the biharmonic ionization amplitudes determines the dominance of a particular beam polarization over another and that it can be controlled by an appropriate choice of beam parameters. Furthermore, we demonstrate our findings for the ionization of neon $L$ shell electrons.
