Pulse corrections obtained with Krotov’s method. The figure summarizes the differences between the optimized pulse, cf. panel (h) in Figure 3, and the (pre-optimized) guess pulse, cf. panel (d) in Figure 3, also indicated by the dashed red/gray line in each panel. The panels from top to bottom show the corrections to absolute value, complex phase, and spectrum of the pulse, respectively (solid black lines). The amplitude, phase, and spectrum of the guess pulse (dashed red/gray lines) are shown using the alternative axis scaling in red/gray.
