| 摘 要： | 本文通过求解一维含时薛定谔方程, 比较研究了H2+和HD+分子离子体系的高次谐波发射效率. 数值计算结果表明, 在相同激光条件下, 不对称分子体系能产生更高强度的谐波谱. 此外, 借助时频分布, 电离几率和电子-核波包密度概率分布图, 对计算结果做出了合理的解释.

| Abstract: | The yields of the molecular high-order harmonics generation is studied by numerically solving the one-dimensional (1D) time-dependent Schrödinger equation (TDSE) when the model H2+/HD+ ions are exposed to an intense laser pulse. To explain the effect more clearly, not only the ionization probabilities but also the electron-nuclear probability density distributions and time-frequency profiles are calculated. The results show that more intense harmonics are generated in the asymmetric diatomic molecule ion HD+ than that of H2+ ion. |
