Abstract

A Cs referenced optical frequency comb system has been used to measure the center frequency of the

5 s {}^{2}S_{1 ∕ 2} - 4 d {}^{2}D_{5 ∕ 2}

transition at

445 THz

in a single, trapped, and laser-cooled

{}^{88}{Sr}^{+}

ion. The transition frequency

ν_{S D} = 444 779 044 095 510 Hz \pm 50 Hz (1 σ)

is obtained, when corrected for systematic shifts. A detailed calculation of the estimated systematic shifts is presented which yields improved values for the various shift parameters including blackbody and electric quadrupole moment shifts.
