The Chip-Scale Atomic Clock – Coherent Population Trapping …
Ramsey spectroscopy with a single ensemble is performed to measure the atom–laser coherence time. The averaged excitation fraction is fitted to a sinusoidal function (Fig. 2b, insets (i) and (ii)) and the corresponding amplitude is extracted as the contrast at each interrogation time. The contrast is then fitted … See more The experiment begins by capturing atoms from a thermal atomic beam in a three-dimensional magneto-optical trap (MOT) operating on the 1S0 → 1P1 transition at 461 nm, which has a linewidth of 32 MHz.

Webadvantage of the available laser coherence time. By means of an optical frequency comb, we transfer the excellent frequency instability of a laser stabilized to a single-crystal cryogenic silicon cavity [18] to the probe laser systems and realize coherent interrogation times of up to 500 ms.
