  Inspired by a recent experiment [Phys. Rev. Letts. \textbf{122},
253201(2019)] that an unprecedented quantum interference was observed in the
way of Stimulated Raman adiabatic passage (STIRAP) due to the coexisting
resonant- and detuned-STIRAPs, we comprehensively study this effect for
uncovering its robustness towards the external-field fluctuations of laser
noise, imperfect resonance condition as well as the excited-state decaying. We
verify that, an auxiliary dynamical phase accumulated in hold time caused by
the quasi-dark state can sensitively manipulate the visibility and frequency of
the interference fringe, representing a new hallmark to measure the hyperfine
energy accurately. The robust stability of scheme comes from the intrinsic
superiority embedded in STIRAP itself, which promises a remarkable preservation
of the quantum interference quality in a practical implementation.
