基于171Yb+在~ 12.6 GHz的基态跃迁的可移动微波频率标准的开发需要一个紧凑的激光系统来冷却离子，清除长寿命状态，也用于光电离。在本文中，我们描述了一种适合的紧凑型激光系统的开发，该系统基于6U高的机架式布置，总体尺寸为260 × 194 × 335 mm。369 nm（用于冷却），399 nm（光电离），935 nm（泵浦）和760 nm（状态清除）的激光输出组合在光纤排列中，以传递到我们的线性离子阱，我们通过冷却171Yb+离子来演示该系统。此外，我们还证明了935 nm和760 nm的激光频率分别接近水蒸气和氧气吸收谱线；具体地说，在760 nm处，我们发现一个171Yb+跃迁位于氧谱线的压增谱线内。这些分子跃迁为171Yb+频率标准激光器的稳定提供了方便的波长参考。
The development of a transportable microwave frequency standard based on the ground-state transition of 171Yb+ at ∼12.6 GHz requires a compact laser system for cooling the ions, clearing out of long-lived states and also for photoionisation. In this paper, we describe the development of a suitable compact laser system based on a 6U height rack-mounted arrangement with overall dimensions 260 × 194 × 335 mm. Laser outputs at 369 nm (for cooling), 399 nm (photoionisation), 935 nm (repumping), and 760 nm (state clearout) are combined in a fiber arrangement for delivery to our linear ion trap and we demonstrate this system by cooling of 171Yb+ ions. Additionally, we demonstrate that the lasers at 935 nm and 760 nm are close in frequency to water vapor and oxygen absorption lines, respectively; specifically, at 760 nm, we show that one 171Yb+ transition is within the pressure broadened profile of an oxygen line. These molecular transitions form convenient wavelength references for the stabilization of lasers for a 171Yb+ frequency standard.
