Generation of incoherent light from a laser diode based on the injection of an emission from a superluminescent diode
Akifumi Takamizawa, Shinya Yanagimachi, Takeshi Ikegami
In this study, incoherent light with a spectral linewidth of 7 nm and 140 mW of power was generated from a laser diode into which incoherent light emitted from a superluminescent d…
Testing Lorentz Invariance with a Double-Pass Optical Ring Cavity
Yuta Michimura, Nobuyuki Matsumoto, Noriaki Ohmae +4
We have developed an apparatus to test Lorentz invariance in the photon sector by measuring the resonant frequency difference between two counterpropagating directions of an asymme…
Prospects for Observing and Localizing Gravitational-Wave Transients with Advanced LIGO, Advanced Virgo and KAGRA
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1319
We present our current best estimate of the plausible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next several years,…
Gapless dual-comb spectroscopy in terahertz region
Takeshi Yasui, Yi-Da Hsieh, Yuki Iyonaga +6
We demonstrated combination of gapless terahertz (THz) comb with dual-comb spectroscopy, namely gapless dual-THz-comb spectroscopy, to achieve the spectral resolution equal to widt…
Precision measurements of the Planck and Avogadro constants
Horst Bettin, Kenichi Fujii, John Man +3
Precision measurements of the fundamental constants are tour de force of basic metrology, where the useful information is usually beyond the last digit of the measured value. They…
New Limit on Lorentz Violation Using a Double-Pass Optical Ring Cavity
Yuta Michimura, Nobuyuki Matsumoto, Noriaki Ohmae +4
A search for Lorentz violation in electrodynamics was performed by measuring the resonant frequency difference between two counterpropagating directions of an optical ring cavity.…
Determining sample alignment in X-ray Reflectometry using thickness and density from GaAs/AlAs multilayer certified reference materials
Donald Windover, David L. Gil, Yasushi Azuma +1
X-ray reflectometry (XRR) provides researchers and manufacturers with a non-destructive way to determine thickness, roughness, and density of thin films deposited on smooth substra…
