Yb+ single-ion optical frequency standard with systematic uncertainty at the 10−17 level

Nils Huntemann, B. Lipphardt, Maksim V. Okhapkin +2 more

The171Yb+ion possesses two transitions that are applicable as references for optical frequency standards and several general features make this ion attractive: All relevant radiations for cooling and excitation can be generated from diode lasers. A nuclear spin of 1/2 ensures a simple sublevel structure. Long storage times of Yb+in ion traps are easily obtained. The2S1/2(F = 0) →2D3/2(F = 2, mF= 0) electric quadrupole transition at 436 nm with a natural linewidth of 3.1 Hz provides a quantum noise limited instability of a single-ion frequency standard of about 2 × 10-15in 1 s. The electric octupole transition2S1/2(F = 0)→2F7/2(F = 3, mF= 0) at 467 nm with a natural linewidth in the nHz range will allow to surpass that instability level. It also possesses a lower sensitivity to field-induced frequency shifts. In this system the Fourier-limited interrogation linewidth can be adapted to that of the best available laser sources, which are presently at the level below 1 Hz. Both transitions have been recommended as secondary representations of the SI second.The171Yb+ion possesses two transitions that are applicable as references for optical frequency standards and several general features make this ion attractive: All relevant radiations for cooling and excitation can be generated from diode lasers.

An optical frequency standard based on the 2 S 1/2 — 2 F 7/2 transition in 171 Yb +

The 2S1/2 (F = 0) - 2F7/2 (F = 3, m F = 0) transition at 467 nm in a single, trapped, laser cooled ion of 171Yb+ has the potential to be an extremely accurate optical frequency reference. Systematic shifts have been evaluated and are currently dominated by the ac-Stark shift. However, this is not expected to be the case as probe laser linewidth is reduced. A heterodyne measurement of the probe laser shows it to have a width of 20 Hz on a 1 minute timescale. The atomic spectrum on the other hand, has been found to have a broadened width of 200 Hz. Using heterodyne detection of light reflected from the trap electrodes, Doppler shifting due to vibration of the trap is identified as the additional source of broadening.The 2S1/2 (F = 0) - 2F7/2 (F = 3, m F = 0) transition at 467 nm in a single, trapped, laser cooled ion of 171Yb+ has the potential to be an extremely accurate optical frequency reference.
