| Abstract: |
| This paper introduces the chipscale atomic clock(CSAC
) based on coherent population trap(CPT) theory. CPT clock is the representative
of ato
mic miniature atomic clock in the future. Standing progress has been made for CP
T clock in designing techniques, manufacturing technology, and physics mechanism
,in recent years. Principle prototype of the CSAC has
been developed. According to the developing trend, product of the CSAC will be
offered to customer in three or five years. |
