Time-dependent orientation factor, 〈cosϕSZ〉(t). Orientation factor as a function of a delay between OTC and the probe pulse for two relative phases ϕL = 0,π. Around t = 0, ionization leads to an increase/decrease in the orientation, while the delayed orientation peaks result from hyperpolarizability interaction. Error bars represent the uncertainty propagated during data analysis according to Gaussian’s propagation law
