For a non-detuned single atom, π-pulse efficiency as a function of the comb aspect ratio ϵ. The π-pulse efficiency is obtained by taking the transition probability at the polychromatic π-time (middle of the first plateau, given by \(\pi /\delta \omega \) in the single-atom case considered here). For combs both with and without a resonant component, the efficiency is maximal at \(\epsilon =1\), which can be seen from Eq. (4). We have used here \(N=10\) pairs of peaks
