摘要

我们报道了一种用于中国空间站87Sr光学晶格时钟的紧凑型光学系统的设计和在轨演示。该系统采用紧凑而坚固的垂直堆叠结构，总容积为0.11 m3，质量为53.6 kg。它通过了热和振动测试，并在发射后保持全面运行。在轨道上，它实现了自动多级激光稳定和87Sr原子的蓝色磁光阱。这标志着在太空中操作光学时钟迈出了重要一步。

Optical system for a strontium optical lattice clock aboard the Chinese Space Station.

We report the design and in-orbit demonstration of a compact optical system for a 87Sr optical lattice clock aboard the Chinese Space Station. This system adopts a compact and robust vertically stacked architecture with a total volume of 0.11 m3 and a mass of 53.6 kg. It passed thermal and vibration qualification tests and remained fully operational after launch. In orbit, it achieved automated multi-stage laser stabilization and a blue magneto-optical trap for 87Sr atoms. This marks a significant step toward operational optical clocks in space.
