An atomic beam optical frequency atomic clock and a producing method thereof includes an atomic oven (1) provided in a vacuum chamber (2) which sprays an atomic beam (8) from a fire hole after heating, a transition laser (4) corresponding to the frequency of the transition excites the atomic beam (8) from a basic state of the transition to an excited state of the transition which passes by means of insulating, and the atomic beam (8) acts with the laser which corresponds to the frequency of the transition. After acting, the atomic beam passes a signal detection region which has a detection laser (5) and acts with the detection laser (5). After acting, each atom emits spontaneous radiating photons, and the fluorescent photon signals which are excited by the detection laser (5) are detected, and the transition laser (4) which is used to detect the frequency of the atomic transition is modulated and the frequency of the transition laser is locked at the transition spectrum of atom by the detected signals, so the atomic clock is realized. |
