Influence of magnetic fields on the bias stability of atomic gyroscope operated in spin-exchange relaxation-free regime

摘要

Highlights?Although the sensitivity to external magnetic fields has been suppressed in the SERF AG through the compensation effect of the polarized nuclear spins, the fluctuations in fields still induce a significant influence on the systematic stability.?A theoretical relationship between the magnetic fields and the AG response is given, and the influence of field fluctuations on the systematic stability is also shown.?This work is especially valuable to the development of SERF AG.AbstractFor the atomic gyroscope (AG) operated in spin-exchange relaxation-free (SERF) regime, the sensitivity to external magnetic fields has been suppressed while the ability to sense inertial rotations has been kept. Here, a theoretical relationship between the magnetic fields and the AG response is given, and the influence of field fluctuations on the systematic stability is also shown.
