Data of Miniaturised optical system for SCSAC

We present a highly stable and miniaturised optical system designed for a caesium satellite-borne cold atom clock (CSCAC). The optical system was integrated on an aluminium-based silicon carbide bench and emitted laser beams with four different frequencies on three fiber ports to capture, cool, prepare, and detect atoms. The optical system, utilizing a compact three-layer optical-mechanical and thermal management design, passed environmental simulation tests and adapted to a special satellite-borne environment. The optical system stability meets the laser requirements of the clock. This dataset included the test data of the miniaturised optical system
