将最优控制理论与瞬态探针吸收光谱理论相结合，应用于弱响应区分子波包动力学的控制和检测。我们得到了一个全局最优的泵转储控制场，该控制场将初始状态驱动到预定义的目标，集中在电子基态电势的内转折点区域。在检测方面，我们计算了积分和色散的瞬态泵浦-转储-探测吸收信号，并采用差分检测方案来揭示最佳控制的分子动力学。
The theory of optimal control together with that of transient probe absorption spectroscopy are applied for control and detection of molecular wave packet dynamics in the weak response regime. We obtain a globally optimal pump–dump control field which drives the initial state to the predefined target, focused at the inner-turning point region of the electronic ground state potential. As for the detection, we calculate both the integrated and the dispersed transient pump–dump–probe absorption signals and adopt the difference detection schemes to reveal the optimally controlled molecular dynamics.
