Embodiment 1
[0029] exist figure 1 Among them, the present invention relates to a small-sized cold atomic clock device used in a timekeeping system. A two-dimensional magneto-optical trap 2 is arranged in the atomic beam emission direction of the atomic furnace 1. The atomic furnace 1 generates rubidium atomic beams by heating, and the rubidium atomic beams Through diffusion into the two-dimensional magneto-optical trap 2, the atomic beam emitted by the two-dimensional magneto-optical trap 2 enters the three-dimensional magneto-optical trap 4 after being collimated by the collimation device 3, and the collimation device 3 of the present embodiment is processed with a through hole Cylindrical structure, the diameter of the through hole is 1mm. The atomic furnace 1, the two-dimensional magneto-optical trap 2, the collimation device 3, and the three-dimensional magneto-optical trap 4 are placed horizontally and the central axes are located in the same horizontal plane.
