Evaluation of a ${}^{88}$Sr${}^{+}$ optical clock with a direct measurement of the blackbody radiation shift and determination of the clock frequency

M. Steinel, H. Shao, M. Filzinger +7

We report on an evaluation of an optical clock that uses the ${}^2{S}_{1/2}\to {}^2{D}_{5/2}$ transition of a single ${}^{88}$Sr${}^{+}$ ion as the reference. In con…
