Optimal robust stimulated Raman exact passage by inverse optimization

We apply the inverse geometric optimization technique to generate an optimal and robust stimulated Raman exact passage (STIREP) considering loss of upper state as a characterization parameter. Control fields temporal shapes that are with respect pulse area, energy, duration, found form simple sequence combination intuitively (near beginning end) counter-intuitively ordered pairs. The resulting dynamics produces which is about third non-robust STIREP. Alternative solutions featuring lower losses, larger areas, fully counter-intuitive sequences derived.
