摘要: 提出了利用微波慢波结构的铷频标制作吸收泡的一种新方法, 不仅可以加强铷原子与微波场的相互作用, 提高 0-0 跃迁谱线的信噪比, 将改善铷频标的稳定度, 还可以增强吸收泡的机械强度, 提高合格率, 特别对在真空下工作的铷频标更为有利。

关键词: 微波慢波结构, 跃迁谱线, 频率稳定度

Abstract: A new way to make the absorption cell of Rb frequency standard using slow-wave structure is suggested. It will increase the interaction between Rb atoms and microwave field, and then the signal to noise ratio of 0-0 transition spectrum and the short term stability will be improved. It is especially useful for Rb frequency standard working in vaccum conditions.

Key words: microwave slow-wave structure, transition spectrum, frequency stability
