All-polarization-maintaining, single-port Er:fiber comb for high-stability comparison of optical lattice clocks
Noriaki Ohmae, Naoya Kuse, Martin E. Fermann +1
All-polarization-maintaining, single-port Er:fiber combs offer long-term robust operation as well as high stability. We have built two such combs and evaluated the transfer noise f…
Continuous-wave, single-frequency 229 nm laser source for laser cooling of cadmium atoms
Yushi Kaneda, J. M. Yarborough, Yevgeny Merzlyak +4
Continuous-wave output at 229 nm for the application of laser cooling of Cd atoms was generated by the 4th harmonic using two successive second harmonic generation stages. Employin…
Frequency ratios of Sr, Yb and Hg based optical lattice clocks and their applications
Masao Takamoto, Ichiro Ushijima, Manoj Das +8
This article describes the recent progress of optical lattice clocks with neutral strontium (Sr), ytterbium (Yb) and mercury (Hg) atoms. In particular, we pr…
Frequency Ratio of Hg and Sr Optical Lattice Clocks beyond the SI Limit
Kazuhiro Yamanaka, Noriaki Ohmae, Ichiro Ushijima +2
We report on a frequency ratio measurement of a Hg-based optical lattice clock referencing a Sr-based clock. Evaluations of lattice light shift, including atomic…
