The Optically Pumped Cs Frequency Standard at the NRLM

S. Ohshima, Y. Nakadan, Y. Koga

Abstract:	The Optically pumped Cs frequency standard is being developed at the NRLM, and the construction is almost finished. Its microwave cavity length is 0.96m, and the dimensions are almost the same as the conventional type frequency standards at the NRLM. Light sources for optical pumping and detection, whose frequencies are stabilized by means of saturated absorption spectra of Cs, are also developed. Using this apparatus, we could observe Ramsey resonance signal and could confirm the two frequency pumping effect. In addition, pumping with polarized laser light, we also confirmed that the magnetic field could be measured using Zeeman coils in the same way of conventional type.
