摘要:

We develop an integrated integrating sphere cold atom clock (ISCAC), which mainly consists of physical package, laser system, microwave source, and electronics. This compact system is more stable and reliable than the previous version. The experimental results show that the short term frequency stability of 5.4×10-13τ-1/2 and 2.9×10-15 at 1-day integrating time are achieved.

Abstract:

We develop an integrated integrating sphere cold atom clock (ISCAC), which mainly consists of physical package, laser system, microwave source, and electronics. This compact system is more stable and reliable than the previous version. The experimental results show that the short term frequency stability of 5.4×10-13τ-1/2 and 2.9×10-15 at 1-day integrating time are achieved.

Key words: integrating sphere cold atom clock, physical package, laser system, frequency stability
