飞秒高分辨率泵浦探测实验与理论从头算量子计算和波包动力学模拟一起用于解码自适应学习算法产生的最佳飞秒脉冲。该脉冲旨在最大限度地提高有机金属离子CpMn(CO)(5)的产量，同时阻碍竞争破碎。目标离子的顺序激发和电离是由两个具有最佳频率和时间延迟的主导子脉冲组成的优化场完成的。
Femtosecond high-resolution pump-probe experiments have been used together with theoretical ab initio quantum calculations and wave packet dynamics simulations to decode an optimal femtosecond pulse that is generated from adaptive learning algorithms. This pulse is designed to maximize the yield of the organometallic ion CpMn(CO)(5) while hindering the competing fragmentation. The sequential excitation and ionization of the target ion are accomplished by an optimized field consisting of two dominant subpulses with optimal frequencies and time delays.
