Paper Abstract

We report the current status of our ytterbium optical lattice clock at the NMIJ, AIST. After the first measurement of the clock transition frequency and the estimation of the uncertainty, we have been improving our clock. For an increased signal to noise ratio of the observed spectrum, we employed an atom number normalization scheme. We stabilized the frequency of the lattice laser using a fiber-based optical frequency comb. We also stabilized the intensity of the lattice laser.
