Abstract

We demonstrate the construction of the optical system in the atomic clock-beyond atomic fountain based on ⁸⁷Rb atom. The optical system includes a high-stability laser system and an optical lattice. The high-stability laser system with the new scheme of frequency locking and shift is introduced in detail, which is an important laser source for laser cooling. The optimized frequency and intensity stability are achieved to 4 × 10^–14 (Formula presented.) ((Formula presented.) is the averaging time) and 4 × 10^–5 (Formula presented.), respectively, which are highly stable. On the basis of the conventional atomic fountain clock, the optical lattice is specially investigated along the direction of gravity and its characteristics are studied systematically. For the optimized and novel exploration, we predict the achievable stability of (Formula presented.) and it has the potential to be improved to (Formula presented.). The realizability of the construction due to the stabilized laser and optical lattice makes the beyond fountain promising candidate for the next-generation high performance microwave atomic clock.
