  • Abstract
    We present work on a frequency standard based on the 2S1/2(F=0, mF=0)rarr2D3/2(F=2, mF=0) electric quadrupole transition in 171Yb+ at 688 THz, and future plans for a frequency standard based on the 2S1/2(F=0, mF=0)rarr2F7/2(F=3, mF=0) electric octupole transition in the same ion at 642 THz. Direct measurement of the ratio of these two frequencies, derived from a single ytterbium ion, constitutes a sensitive test for the temporal constancy of the fine structure constant.
