论文摘要
我们报告基于激光冷却171yb+离子陷阱系统的微波频率标准的进度。电子，激光器和磁性防护罩被整合到单个物理包装中。超过1E5离子被稳定地捕获，该系统提供了高信噪比Ramsey线形。与以前的工作相比，171yb+微波钟的频率不稳定性进一步提高到$ 8.5 \ times {10^{ - 13}}/\ sqrtτ$，对于10到1000 s之间的平均时间。
We report on progress towards a microwave frequency standard based on a laser-cooled 171Yb+ ion trap system. The electronics, lasers, and magnetic shields are integrated into a single physical package. With over 1E5 ions are stably trapped, the system offers a high signal-to-noise ratio Ramsey line-shape. In comparison with previous work, the frequency instability of a 171Yb+ microwave clock was further improved to $8.5 \times {10^{ - 13}}/\sqrt τ$ for averaging times between 10 and 1000 s.
