A kind of cpt atomic clock frequency taming control method and equipment

Abstract

The present application discloses a CPT atomic clock frequency taming control method and equipment, including: the CPT atomic clock includes a taming controller, the taming controller determines the local oscillator frequency of the CPT atomic clock, and obtains the second frequency based on the frequency division of the local oscillator frequency. A second pulse signal; receiving a second second pulse signal input through an external port; based on the first second pulse signal and the second second pulse signal, determining the local oscillator frequency of the CPT atomic clock within a set time interval Frequency offset; according to the frequency offset, the local oscillator frequency of the CPT atomic clock is tamed and adjusted, so as to tame the frequency of the CPT atomic clock in a short period of time, so as to suppress the frequency drift of the CPT atomic clock, and through the built-in CPT atomic clock The realization of the taming controller has a simple structure and is easy to debug, which improves the automatic control and autonomous operation of the CPT atomic clock frequency taming.

Description

technical field [0001] The present application relates to the technical field of atomic clocks, in particular to a CPT (Coherent Population Trapping, Coherent Population Trapping) atomic clock frequency taming control method and equipment. Background technique [0002] Atomic clocks are currently the most accurate timekeeping tools in the world. It plays an important role in communications, aerospace, satellite navigation and scientometric testing. CPT atomic clock is a new type of atomic clock designed based on the coherent population and confinement principle of atoms. It mainly uses two-color coherent light to interact with atoms to prepare atoms into a coherent state, and uses CPT signals as microwave frequency discrimination signals to realize atomic clock frequency resources. [0003] CPT atomic clock is different from traditional atomic clocks such as hydrogen, rubidium, and cesium in terms of working principle. The quantum part does not require a microwave resonator...
