Alignment dependent ultrafast electron-nuclear dynamics in high-order harmonic generation

Mu-Zi Li, Guang-Rui Jia, Xue-Bin Bian

We investigated the high-order harmonic generation (HHG) process of diatomic molecular ion ${\mathrm{H}}_2^{+}$ in non-Born-Oppenheimer approximations. The corresponding three-dimensio…
