The Rb-Xe coupling effect in optically pumped NMR gyroscopes

Due to the Rb-Xe coupling effect in the optically pumped NMR gyroscope, the Xe NMR frequency changes with the carrier frequency and demodulation phase of the Rb magnetometer as described in the two pictures above, which could reduce the magnetic field fluctuation suppression efficiency of the dual Xe species scheme and this adverse effect can be improved through our phase difference locking scheme as described in the two pictures below.
