The experimental results using a new scheme of stimulated Raman shortcut-to-adiabatic passage (STIRSAP) to implement an atom interferometer and improve its robustness are reported. The fringe contrast of the Ramsey atom interferometer using STIRSAP is analyzed. Compared with the traditional Ramsey interferometer using stimulated Raman adiabatic passage, the adiabatic passage is speeded up in the STIRSAP, and the contrast of the atom interference fringe is improved. By tuning the intensity of pump and Stokes light pulse, the phase shift of the atom interference fringe caused by the AC Stark effect is investigated. The experimental results show that the STIRSAP can effectively suppress AC Stark effect in the atomic interference, and thus improve the robustness of atom interferometer.
