Demonstration of length control for a filter cavity with coherent control sidebands
Naoki Aritomi, Yuhang Zhao, Eleonora Capocasa +22
For broadband quantum noise reduction of gravitational-wave detectors, a frequency-dependent squeezed vacuum field realized using a filter cavity is the most promising technique an…
Improving the stability of frequency dependent squeezing with bichromatic control of filter cavity length, alignment and incident beam pointing
Yuhang Zhao, Eleonora Capocasa, Marc Eisenmann +21
Frequency dependent squeezing is the main upgrade for achieving broadband quantum noise reduction in upcoming observation runs of gravitational wave detectors. The proper frequency…
Cryogenic suspension design for a kilometer-scale gravitational-wave detector
Takafumi Ushiba, Tomotada Akutsu, Yoichi Aso +43
We report the mirror suspension design for Large-scale Cryogenic Gravitational wave Telescope, KAGRA, during bKAGRA Phase 1. Mirror thermal noise is one of the fundamental noises f…
Investigation of crackling noise in the vibration isolation systems of the KAGRA gravitational wave detector
Yuhang Zhao, Shin Kirii, Yingtao Liu +3
Gravitational wave detectors, such as KAGRA, require complex mirror suspension systems to reach high sensitivity. One particular concern in these suspensions is the presence of cra…
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…
Mirror actuation design for the interferometer control of the KAGRA gravitational wave telescope
Yuta Michimura, Tomofumi Shimoda, Takahiro Miyamoto +36
KAGRA is a 3-km cryogenic interferometric gravitational wave telescope located at an underground site in Japan. In order to achieve its target sensitivity, the relative positions o…
