冷镱原子精密光谱的研究进展

Advances in the precision spectroscopy of cold ytterbium atoms

文章简要介绍了冷原子精密光谱研究方面的重要进展,报道了作者所在课题组近年来在镱原子的激光冷却与囚禁、光晶格中冷镱原子的量子操控、冷镱原子钟跃迁谱的精密测量、冷镱原子光钟的闭环锁定和频率稳定性测量等方面所取得的最新研究结果,最后对光学原子钟的发展进行了展望。

Significant progress in the precision spectroscopy of cold atoms has been made in recent years. We report the latest results in our group on laser cooling and trapping of ytterbium atoms, quantum manipulation of cold ytterbium atoms in an optical lattice, precision measurement of the clock-transition spectrum, and laser stabilization to the clock transition and its frequency instability measurement. The future prospects of optical atomic clocks are also reviewed.
