a Illustration of the polarization-dependent transitions in the multi-level quantum system. b The oscillation of \({I}_{4}^{{{{{{\rm{FID}}}}}}}\) as a function of delay τ under different polarization angle θ. The dashed red line illustrates the phase shift of the intensity oscillation. c The interference visibility M4 as a function of θ. The red solid line represents the model results. d The oscillating phase of the 5s state δϕ4 as a function of θ. The red solid line represents the model results. The error bars in c and d are determined by the fitting errors. e The model results of the population on the intermediate states of different magnetic sublevels M = 0, ±1.
