Frequency lock-in-induced deadband phenomena are major problems of ring laser gyroscopes (RLGs), which deteriorate linear responses to changes in the applied rotation rate. In this work, the frequency lock-in phenomenon occurring in the RLG was succe

We have developed an atom spin gyroscope that uses a Rb–Xe vapor cell. The signal-to-noise ratio (SNR) and the angular random walk (ARW) of a Rb-natural Xe– $$\hbox {N}_2$$ vapor cell and a Rb– $$^{129}$$ Xe– $$^{131}$$ Xe– $$\hbox {N}_2$$

For small ring laser angle sensors that have several tens of centimeters of laser cavity perimeter, the laser cavities must be vibrated using uncorrelated white angular vibration in order to overcome the dead band. However, due to the high Q-factor s

We designed a double-layered polyimide film heater where the direction of the injection current of each layer is opposite to that of the other layer to reduce the magnetic field. The width of the heater is 0.125 mm and the resistance is 21.2 Ω. This

We generated a continuous cold atomic beam using a two-dimensional magneto-optical trap for atom interferometry. The vacuum system is made of Zerodur glass with a large optical access for a compact system.
