飞秒激光强场条件下碘化钠分子解离过程的理论研究

Theoretical Study of the Femtosecond Photodissociation of the NaI Molecule

我们采用了精确的量子力学方法对飞秒激光强场条件下碘化钠分子的解离过程进行了理论研究.从计算结果中我们可以得到两个结论:第一,当泵浦-探测延迟时间超过300飞秒的时候,碘化钠分子开始光解离;第二,随着延迟时间的增加,有越来越多的处于激发态上的碘化钠分子被光解离.

The femtosecond photodissociation of the NaI molecule is studied by using accurate quantum mechanics method.Two conclusions can be drawn from the calculations.First,the photodissociation of the NaI molecule begins when the delay time is longer than 300 fs.Second for the excited state of NaI molecule,more and more NaI molecules photodissociate with the increasing delaytime.
