Description

technical field [0001] The invention relates to the technical field of atomic clock operation state monitoring, in particular to a method and device for atomic clock operation state monitoring. Background technique [0002] In scientific research or experiments, the time requirements are very strict, and ordinary clocks cannot meet the precision requirements of scientific research or experiments, and atomic clocks are usually used. [0003] Atomic clocks use the principle of atomic physics. Atoms absorb or release electromagnetic energy according to the energy difference of different electronic arrangement sequences, that is, the energy difference of different electron layers around the nucleus. Here, the electromagnetic energy is discontinuous. When the atom When it transitions from an "energy state" to a low "energy state", it will release electromagnetic waves. The characteristic frequency of this electromagnetic wave is discontinuous, that is, the resonance frequency. ...

Problems solved by technology

[0004] Moreover, during the operation of many atomic clocks, in order to keep the operating state stable, they often use a magnetic field to compensate, but the magnetic field can only increase the frequency value of the integrated filter resonant bubble system, and cannot reduce its frequency value. In this way, the integrated filter of the atomic clock The interior of the optical resonance bubble works in a constant temperature environment of 60°C-70°C for a long time. When the pumping light passes through, the internal atoms continue to undergo physical effects such as resonance and collision. After such a long-term work, the frequency of the integrated filter resonance bubble may change. , so that the atomic clock cannot achieve normal closed-loop locking, and it is also impossible to monitor the operating status of the atomic clock in real time
