Web1 Jan 2024 · With this probing laser for a single 40 Ca + ion, the resolution of Zeeman spectrum components is evaluated to be about 22 Hz with a probe pulse time of 40 ms. The clock fractional frequency instability is measured to be 3.4×10 −14 / τ1/2 (1~10,000 s) with a probe pulse time of 20 ms by clock self-comparison. Section snippets Experimental setup WebHere we present a liquid nitrogen-cooled Ca + optical clock with an overall systematic uncertainty of 3×10 -18. In contrast with the room-temperature Ca+ optical clock that we have reported previously, the temperature of the blackbody radiation (BBR) shield in vacuum has been reduced to 82 (5) K using liquid nitrogen.
