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.
