Vibration-proof CSAC (chip-scale atomic clock) physical system

The invention discloses a vibration-proof CSAC (chip-scale atomic clock) physical system, which solves the problems that existing chip-scale atomic clocks are complicated in structure, high in cost and energy consumption, and the like. The vibration-proof CSAC physical system comprises an LCC base, a VCSEL (vertical cavity surface emitting laser) carrier, a VCSEL module, a ceramic skeleton, a photocell and a ceramic sealing cap, wherein the VCSEL carrier is welded on the LCC base, the VCSEL module is arranged on the VCSEL carrier, the ceramic skeleton is located above the VCSEL carrier and the lower end of the ceramic skeleton is fixed on the LCC base, the photocell is arranged at the upper end of the ceramic skeleton, and the ceramic sealing cap is used for carrying out vacuum seal on each component in cooperation with the LCC base; and the ceramic skeleton is hollow, an electrode routing for transmitting electrical signals is arranged on the surface of the ceramic skeleton, and a 1/4 slide, a Polaroid and a bubble-absorbing module are sequentially arranged in the ceramic skeleton from bottom to top. The vibration-proof CSAC physical system disclosed by the invention is simple in structure and low in production cost, and a solid foundation is laid for the large-scale popularization and application of the physical system.
