Status report on an <sup>171</sup>Yb optical lattice clock at NMIJ
説明
We report the status of our 171Yb optical lattice clock. The frequency stability of the Yb lattice clock is $1\times10^{-14}(\tau$/s)-1/2 where $\tau$ is an averaging time. The systematic uncertainty of the Yb lattice clock is evaluated to be $3.6\times10^{-16}$. Towards contribution to the International Atomic Time, some contrivances are incorporated in order for the Yb lattice clock to run for a long term. For example, automatic relocking schemes are recently prepared for phase locking and injection locking.
