WebFor this measurement, the optical clock frequency data measured with respect to the H-maser by the comb is calibrated by the optical clock frequency of 1 S 0-3 P 0. For each measurement, the Hz-levels of 578 nm transition spectra are detected, from which the 578 nm frequency measured by the comb is calibrated. WebOct 20, 2024 · Optical lattice clocks benefit from a large number of interrogated atoms, which naturally reduces the frequency instability. Still, optical lattice clocks require a complex loading scheme from a Zeeman slower or a 2D magneto-optical pre-loading trap. The optical trap is shallow, needs accurate adjustments and is sensitive to vibrations.
