Chapter 28 The Electronic System of ~(87)Rb CPT Maser Atomic Clock

摘要

We present the electronic system, together with the physical package, of the ~(87)Rb CPT maser atomic clock, which is related to the coherent population trapping phenomenon. Moreover, frequency locking of our experimental apparatus was also developed based on this system. Our results show that the measured short-term frequency stability (Allan deviation) is better than 2 × 10~(-12) τ~(-1/2) from 1 to 100 s.
