Abstract:
We present an experimental study of the lattice-induced light shifts on the S01→P03 optical clock transition (νclock≈518  THz) in neutral ytterbium. The “magic” frequency νmagic for the Yb174 isotope was determined to be 394 799 475(35)  MHz, which leads to a first order light shift uncertainty of 0.38 Hz. We also investigated the hyperpolarizability shifts due to the nearby 6s6pP03→6s8pP03, 6s8pP23, and 6s5fF23 two-photon resonances at 759.708, 754.23, and 764.95 nm, respectively. By measuring the corresponding clock transition shifts near these two-photon resonances, the hyperpolarizability shift was estimated to be 170(33) mHz for a linear polarized, 50  μK deep, lattice at the magic wavelength. These results indicate that the differential polarizability and hyperpolarizability frequency shift uncertainties in a Yb lattice clock could be held to well below 10−17.
