Optical atomic clock review
WebSep 26, 2016 · In addition, we report on the construction of a compact clock laser system that is powered with a single diode laser that provides sufficient power via optical fibres for frequency stabilisation ... WebMar 5, 2024 · This issue would seem to present a dilemma: Adding atoms to the optical lattice provides a larger ensemble and therefore a higher precision measurement. But it also exacerbates the role of atom-atom interactions, which modify the clock-transition frequency in direct proportion to the atomic density [ 8, 9 ].
