Abstract:
We report the results of experimental investigations aimed at creation of the optical frequency standard based on magnesium atoms cooled and localised in a magneto-optical trap (MOT). An experimentally realised MOT for magnesium made it possible to obtain a cloud comprising ~106 – 107 atoms at a temperature of 3 – 5 mK. The results of ultra-high resolution spectroscopy of intercombination 1S0 – 3P1 transition for Mg atom are presented, the resonances in time-domain separated optical fields with the half-width of Γ = 500 Hz are recorded, which corresponds to the Q-factor of the reference line Q = ν/Δν ~1.3 × 1012.
Keywords:
laser cooling, magnesium, frequency standard.
