Abstract : The problem of calculating transition probabilities in twolevel systems is studied in the limit where the detuning is large compared to the inverse duration of the interaction. Within each family, transition probabilities may be calculated from formulae that differ only in the numerical value of a scaling parameter. In cases where the coupling function has a pole in the complex time plane, the families are identified with the order of this singularity. In particular, for poles of first order, a connection with the RosenZenet solution can be made. The analysis is performed via highorder perturbation expansions, which are shown to always converge for twolevel systems driven by coupling potentials of finite pulse area.
