Paper Abstract

Optical clocks surpass the primary Cs microwave clocks with excellent performances. This allows new studies both in fundamental physics and engineering. The paper presents the optical system for our space optical clock at NTSC. Different from it in the laboratory, novel approaches and techniques were used to meet the space requirement of compactness and reliability. The modular consisting of three robust subunits was developed, which was one laser sources breadboard and two optical paths systems breadboards. The compact dimension of the optical system is 540mm×440mm×130mm and the total mass was approximate 28 kilogram. The deformation of two optical paths systems was calculated under an overload test by a mechanical analysis and it could meet the requirement. It is a advancement from lab to engineering application based on the work, which provides effective foundation for improving the optical system.
