Simulation analysis of hydrogen atomic clock double state-selection beam optical system

Abstract: Hydrogen maser utilises transition frequency of hydrogen atom in hyperfine energy level of ground state for precise timing. It has excellent frequency stability, especially in medium and short-term, and low frequency drift. It has been used as high-precision frequency standard in engineering fields such as time keeping, navigation, and very long baseline interferometry. Clock transition of hydrogen maser is transition between states of |F=1, m<sub>F</sub>=0> and |F=0, m<sub>F</sub>=0… Show more
