摘要

通过数值求解非玻恩-奥本海默近似时变薛定谔方程，研究了分子高次谐波产生中的干涉最小值。结果表明，在激光脉冲作用下，氢分子离子在高次谐波谱中出现两种干涉极小值。此外，通过调整激光的波长和原子核的初始条件，发现分子结构和激光场诱导的电子动力学行为分别导致了两种最小干涉。此外，还计算了时频分布和电子波包分布，以便更好地理解最小值的产生机理。

Theoretical exploration of the interference minimum in molecular high-order harmonic generation

The interference minimum in the molecular high-order harmonic gener- ation is studied by numerically solving the non-Born-Oppenheimer approximation time-dependent Schrodinger equation. The results show that two kinds of interference minima appear in the high-order harmonic spectrum when the hydrogen molecular ion is exposed to the laser pulse. Furthermore, by adjusting wavelength of the laser as well as initial condition of nucleus, it is found that two kinds of interference minima are ascribed to the molecular structure and the electronic dynamics behavior induced by the laser field, respectively. Besides, the time-frequency distributions and the elec- tron wave packet distributions are calculated to better understand the mechanism of the minimum.
