Cyclic-Quadrature Intracavity Signal Amplification for Gravitational-Wave Detectors
Kaido Suzuki, Ryo Iden, Ken-ichi Harada +1
The high-frequency sensitivity of laser-interferometric gravitational-wave detectors is limited by quantum shot noise. Increasing the circulating optical power reduces shot noise,…

Observation of an Optical Spring in a Robustly Controlled Signal-Recycled Michelson Interferometer
Kaido Suzuki, Ken-ichi Harada, Ryo Iden +4
We present, to the best of our knowledge, the first demonstration of an optical spring in a signal-recycled Michelson interferometer without arm cavities. The setup utilizes multip…

Photothermal effect in macroscopic optomechanical systems with an intracavity nonlinear optical crystal
Sotatsu Otabe, Kentaro Komori, Ken-ichi Harada +3
Intracavity squeezing is a promising technique that may improve the sensitivity of gravitational wave detectors and cool optomechanical oscillators to the ground state. However, th…
