Compact Frequency Standard Based on an Intra-cavity Sample Cold Cesium Atoms
We have demonstrated the possibility for a compact frequency standard based on a sample of cold cesium atoms. In a cylindrical microwave cavity, the atoms are cooled and interrogated during a free expansion and then detected. The operation of this experiment is different from conventional atomic fou...

| description | We have demonstrated the possibility for a compact frequency standard based
on a sample of cold cesium atoms. In a cylindrical microwave cavity, the atoms
are cooled and interrogated during a free expansion and then detected. The
operation of this experiment is different from conventional atomic fountains,
since all the steps are sequentially performed in the same position of space.
In this paper we report the analysis of a Ramsey pattern observed to present a
47 Hz linewidth and a stability of 5x10^-13 for an integration time longer than
100s. Some of the main limitations of the standard are analyzed. This present
report demonstrates considerable improvement of our previous work (S. T. Muller
et al, J. Opt. Soc. Am. B, v.25, p.909, 2008) where the atoms were in a free
space and not inside a microwave cavity. |
