Using the classical ensemble model, we systematically investigate strong-field nonsequential double ionization (NSDI) of Mg by intense elliptically polarized laser pulses with different wavelengths. Different from the noble atoms, NSDI occurs for Mg driven by elliptically and circularly polarized laser fields. Our results show that in elliptically and circularly polarized laser fields, the NSDI yield is sharply suppressed as the wavelength increases. Interestingly, the correlated behavior in the electron momentum spectra depends sensitively on the wavelengths. The corresponding electron dynamics is revealed by back tracing the classical trajectory.

镁强场非序贯双电离中的相关电子动力学

使用经典的集成模型，我们通过不同波长的强椭圆偏振激光脉冲系统地研究了镁的强场非序贯双电离（NSDI）。与贵族原子不同，NSDI发生在由椭圆和圆偏振激光场驱动的Mg中。我们的结果表明，在椭圆偏振和圆偏振激光场中，随着波长的增加，NSDI的产量会急剧下降。有趣的是，电子动量谱中的相关行为敏感地取决于波长。通过回溯经典轨迹可以揭示相应的电子动力学。
