We study the application of nonlinear wave packet interferometry to the preparation and resolution of the overlaps of nonstationary nuclear wave functions evolving in an excited electronic state of a diatomic molecule. It is shown that possible experiments with two phase-locked ultrashort pulsepairs can be used to determine a specific vibrational wave packet state in terms of coherent states of the ground electronic state. We apply this scheme to an idealized molecule with harmonic potential energy surfaces and to the X <-- B transition states of the iodine molecule. Our results indicate that this scheme is very promising as a potential tool to quantum control.
我们研究了非线性波包干涉测量法在双原子分子激发电子态中演化的非定常核波函数重叠的制备和分辨方面的应用。结果表明，利用两个锁相超短脉冲对进行的可能实验可用于根据基态电子态的相干态来确定特定的振动波包态。我们将此方案应用于具有谐振势能面的理想化分子以及碘分子的X←B跃迁态。我们的结果表明，该方案作为一种潜在的量子控制工具非常有前景。
