我们提出了一种紧凑而可靠的780 nm激光系统，用于基于Rb原子干涉的星载原子惯性传感器。该系统的工作原理是将1560 nm波长的电信光纤倍频。使用相同的激光光源实现磁光囚禁、物质波干涉和原子探测。实现了一台原子重力仪，并在超重力和微重力条件下对激光系统进行了验证。
We propose a compact and robust laser system at 780 nm for onboard atomic inertial sensors based on rubidium atom interferometry. The principle of this system consists in doubling the frequency of a telecom fiber bench at 1560 nm. The same laser source is used to achieve a magneto-optical trap, matter-wave interferences, and the atomic detection. An atomic gravimeter has been realized and the laser system has been validated under hyper- and microgravity.
