We present the long-term stability of the integrating sphere cold atom clock(ISCAC) and analyze its systematic limitations. The relative frequency instability of 2.6 脳 10^(-15) is reached for an averaging time of 2 脳10~5 s. The second-order Zeeman effect and the cavity pullin...
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 ...
Integrating sphere cold atom clock•A novel angled incident method for diffuse laser cooling is presented and compared with the normal injection scheme.•The new method cools more atoms in the sphere, thereby improves the SNR of the clock signal.•The loading time for the angled injection ...

Cold atomintegrating spherecold atomic clocksAn integrating sphere with a diameter of 10 cm is developed for cooling atoms. The maximum number of 2 u00d7 1010 cold atoms is obtained from a background vapor with 220 mW cooling laser power. The cold atom number can be increased by further ...
Number evolutions of residual cold atoms under different kinds of acceleration have been studied in detail. Sequence laser pulse cooling is key technique for the successive operation of cold atom clock. The process of laser pulse cooling is numerically simulated and fitted with experiments, optimized ...
