  •  台站式重力仪（Stationary Atom Gravimeters）

      We developed the world's first 85Rb atomic absolute gravimeter, which participated in the 10th International Comparison of Absolute Gravimeters (ICAG2017, Beijing). The data were adopted by the International Bureau of Weights and Measures, and two new systematic error mechanisms—AC Stark shift imbalance and Raman laser chirp—were discovered [P.W. Huang et al., Metrologia 56, 045012 (2019)]. The 85Rb atomic absolute gravimeter also took part in the 11th International Comparison of Absolute Gravimeters (ICAG2023, Boulder, USA) [H. R. Zhu, et al., Opt. Express, 32(15), 26157(2024)].

  • 水平式原子重力梯度仪（Horizontal Atom Gravity Gradiometers）
  • 竖直式原子重力梯度仪（Vertical Atom Gravity Gradiometers）

    We have developed the world's smallest atomic absolute gravity gradiometer. Currently, the world's smallest atomic gravity gradiometer features a probe height of 0.92 m, a probe volume of 95 liters, and an accuracy of 0.86 E [W. Lyu et al., Phys. Rev. Appl. 18, 054091 (2022)].

  • 原子干涉陀螺装置（Atom Interferometry Gyroscope Setup）

     We report a Mach-Zehnder-type dual-atom-interferometer gyroscope with an interrogation arm of 40-cmlength and the interference area up to 1.2 cm2. The sensor presents a sensitivity of 1.5 × 10−7 rad/s/Hz1/2, and a stability of 9.5 × 10−10 rad/s at 23000 s [Z. W. Yao, et al., Phys. Rev. A 103, 023319(2021)].
