摘要：

A Cs referenced optical frequency comb system has been used to measure the center frequency of the 5s S-2(1/2)-4d D-2(5/2) transition at 445 THz in a single, trapped, and laser-cooled Sr-88(+) ion. The transition frequency nu(SD)=444 779 044 095 510 Hz+/-50 Hz (1sigma) 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.
