We address the challenge of finding the optimal laser intensity and wavelength to drive high-energy, strong field rescattering and report the maximum yields of K-shell and ${{\rm{L}}_{\rm{I}}}$-shell hole creation. Surprisingly, our results show laser-driven rescattering is able to create inner shell holes in all atoms from lithium to uranium with the interaction spanning from the deep IR to x-ray free electron laser sources. The calculated peak rescattering follows a simple scaling with the atomic number and laser wavelength. The results show it is possible to describe the ideal laser intensity and wavelength for general high-energy laser rescattering processes.

强场激光再散射的内壳激发：高能再碰撞的最佳激光条件

我们解决了寻找最佳激光强度和波长以驱动高能、强场再散射的挑战，并报告了 K-shell 和${{\rm{L}}_{\rm{I}}}$的最大产量-壳孔创建。令人惊讶的是，我们的结果表明，激光驱动的再散射能够在从锂到铀的所有原子中产生内壳孔，相互作用范围从深红外到 X 射线自由电子激光源。计算出的峰值再散射遵循原子序数和激光波长的简单缩放。结果表明，可以描述一般高能激光再散射过程的理想激光强度和波长。
