摘要

原子喷泉钟是具有重要应用价值的冷原子装置,紧凑型光学系统设计是研制可搬运冷原子喷泉钟的关键技术之一。介绍了一种以通用铝型材搭建的网格化光学平台,并基于此平台实现了 85Rb喷泉钟紧凑型光路。通过仿真,证明了该型材网格平台在二维方向均具有较好的力学性能。在该平台上,设计并搭建了四倍频移、注入锁定放大、冷却光路、再泵浦光路和探测光路等单元模块,满足了喷泉钟的所有要求。该网格平台面积为50 cm×50 cm,高度为2.5~3 cm。该光路实现了8个月以上的持续运行,功率的起伏小于5%。基于该紧凑型光学系统,完成了后续的 85Rb喷泉钟的物理实验和微波实验。

Abstract

The atomic fountain clock is one cold atom applied apparatus possessing important applications. Compact laser system design is one of the key techniques for a portable cold atomic fountain clock. This paper introduces a gridded optical platform built with the general aluminum profiles, and based on it, we construct a compact optical path for the 85Rb fountain clock. Through simulation, it is proved that the profile gridded platform has better mechanical properties in two-dimensional direction. On this platform, we design and build the modules of such as four-pass frequency shift, injection locked amplifier, cooling optical path, repumping and probing paths to satisfy all requirements of an atomic fountain clock. The platform covers an area of 50 cm×50 cm and has a height of 2.5-3 cm. The optical path has been running continuously for more than 8 months with a power fluctuation less than 5%. Based on the compact optical system, we have completed the subsequent physical and microwave experiments of 85Rb fountain clocks.
