Abstract

The present status of the development of an87Sr optical lattice clock at NMIJ is reported. We also describe our frequency doubling system with a periodically poled lithium niobate waveguide for the first stage cooling laser at 461 nm.

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.

We report on the development of an ytterbium (171Yb) and a strontium (87Sr) optical lattice clock at the National Metrology Institute of Japan (NMIJ). The result of absolute frequency measurement of the171Yb lattice clock is shown. We also report on narrow-linewidth fiber-based frequency combs that are used not only to measure the absolute frequency of the optical lattice clocks but also to servo control the frequency of the lasers for cooling and trapping Yb and Sr atoms.
