Abstract: An alkali-metal vapor cell atomic clock system, including a first atomic vapor cell and a second atomic vapor cell. A digital signal processor outputs a first time sequence to control a first laser signal, and the digital signal processor outputs a second time sequence to control a second laser signal. Thereby, the first atomic vapor cell and the second atomic vapor cell can alternately lock a crystal oscillator. A Dick effect is reduced by alternately locking the crystal oscillator, which enables the alkali-metal vapor cell atomic clock system to have more stable frequency output. Because the crystal oscillator has low costs, the alkali-metal vapor cell atomic clock system has advantages of low costs and high stability.
