Extra -thin chip atomic clock physical system

The utility model discloses an extra -thin chip atomic clock physical system has solved that present chip level atomic clock structure is duplicated, cost and the high scheduling problem that consumes energy. This extra -thin chip atomic clock physical system includes the LCC base, fixes the physics support frame in the LCC base, sets up VCSEL system and photocell in the relative both sides of physics support frame respectively to and use the ceramic sealing cap that carries out each part vacuum seal with the cooperation of LCC base, still be provided with the slide system and absorb the bubble system between VCSEL system and photocell, wherein, the VCSEL system is close to by the slide system, absorbs the bubble system and is close to the photocell, be provided with the electrode and the pad of switching lead wire on the physics support frame, signal on the physics support frame passes through the wiring gold wire and switchovers on the lead wire electrode of LCC base. The utility model discloses simple structure, low in production cost for its popularization and application on a large scale, have established the solid foundation.
