Temporal PE profile as function of the control pulse area \(\propto \sqrt{{I}_{{\rm{C}}}}\): a, b experimental data for contol pre- and post-pulses; c, d corresponding simulations. The delay times for the pre- or post-pulses correspond to 33 and 27 ps, respectively, τ12 = 80 ps, Θ1 ≈ π/2, and Θ2 ≈ π. e Temporal PE profiles for three different pre-pulse intensities IC corresponding to ΘC = π/3 (blue), 3π/4 (red), and 2π (green). Symbols and lines correspond to experiment and modeling, respectively. The associated intensities are labeled with arrows in a.
