摘要The optical frequency of the
4s2S1/2–3d2D5/2 transition in a single trapped and laser−cooled 40Ca+ ion is measured with an optical frequency comb system referenced to a hydrogen maser. A 729−nm laser can be locked to the clock transition about ten hours and the Allan deviation is better than 2×10-14/1000s.
