An arm length stabilization system for KAGRA and future gravitational-wave detectors
T. Akutsu, M. Ando, K. Arai +198
Modern ground-based gravitational wave (GW) detectors require a complex interferometer configuration with multiple coupled optical cavities. Since achieving the resonances of the a…
Construction of KAGRA: an Underground Gravitational Wave Observatory
T. Akutsu, M. Ando, S. Araki +222
Major construction and initial-phase operation of a second-generation gravitational-wave detector KAGRA has been completed. The entire 3-km detector is installed underground in a m…
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…
Real-time geopotentiometry with synchronously linked optical lattice clocks
Tetsushi Takano, Masao Takamoto, Ichiro Ushijima +7
According to the Einstein's theory of relativity, the passage of time changes in a gravitational field. On earth, raising a clock by one centimetre increases its tick rate by 1.1 p…
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…
Higher order test of Lorentz invariance with an optical ring cavity
Yuta Michimura, Jake Guscott, Matthew Mewes +5
We have developed an apparatus to search for the higher-order Lorentz violation in photons by measuring the resonant frequency difference between two counterpropagating directions…
