摘要: We present an alternative scheme for determining the frequencies of cesium (Cs) atom 6S-8S Doppler-free transitions. With the use of a single electro-optical crystal, we simultaneously narrow the laser linewidth, lock the laser frequency, and resolve a narrow spectrum point by point. The error budget for this scheme is presented, and we prove that the transition frequency obtained from the Cs cell at room temperature and with one-layer μ-metal shielding is already very near that for the condition of zero collision and zero magnetic field. We point out that a sophisticated linewidth measurement could be a good guidance for choosing a suitable Cs cell for better frequency accuracy. 其他題名: Opt Lett 出版者: United States: Optica Publishing Group 出版日期: 2013-08-15 出處: Optics Letters, 2013-08, Vol.38 (16), p.3186- 資源來源: Optica Publishing Group Journals 識別號: ISSN: 0146-9592 識別號: ISSN: 1539-4794 識別號: EISSN: 1539-4794 識別號: DOI: 10.1364/ol.38.003186 識別號: PMID: 24104683
