Research highlights and news

Hello world!

I am an experimental astrophysicist with the main focuse set on gravitational wave searches and precision laser interferometry. My ultimate goal is to directly probe the very early Universe by observing primordial gravitational-wave backgrounds. I am currently an associate professor in the Space Astronomy and Astrophysics Department of ISAS, working for LISA, KAGRA and SILVIA by conduting a number of laboratory-scale experiemnts.

If you are interested in joining our group at ISAS in JAXA, please feel free to contact me.

Hobbies: reading, bonfiring, guitar (electric and acoustic) , studying Yokai

Demonstration of tilt sensing using a homodyne quadrature interferometric translational sensor

Koji Nagano, Karera Mori, Kiwamu Izumi

Classical and Quantum Gravity, 42(10) 105007-105007, May 14, 2025 Peer-reviewed

Abstract Future gravitational wave observation in space will demand improvement in the sensitivity of the local sensor for the drag-free control. This paper presents the proposal, design, and demonstration of a new laser interferometric sensor named Quadrature Interferometric Metrology of Translation and Tilt (QUIMETT) for the drag-free local sensor. QUIMETT enables simultaneous measurements of both translational displacement and tilts of a reflective object with a single interferometer package. QUIMETT offers a characteristic feature where the sensitivity to tilt is independent of the interference condition while maintaining the ability to measure the translational displacement for a range greater than the laser wavelength. The tilt-sensing function has been demonstrated in a prototype experiment. The tilt sensitivity remained unchanged in different interference conditions and stayed at 10 nrad Hz at 0.1 Hz.

Angular response of a triangular optical cavity analyzed by a linear approximation method

Satoshi Tanioka, Gui-guo Ge, Keiko Kokeyama, Masayuki Nakano, Junegyu Park, Kiwamu Izumi

Feb 7, 2020

A triangular optical cavity is often used as a mode cleaning cavity in precision laser interferometry such as gravitational wave detectors. An alignment sensing and control system for maintaining the alignment of a mode cleaning cavity with respect to the incoming laser beam is critical for detector's performance. Therefore, understanding the behavior of the angular response is vital to both design and commissioning test of the alignment control system. We present a linear approximation approach which not only simplifies the computation but also provides a comprehensive picture of the angular response. The observable degrees of freedom in a triangular cavity is discussed based on the linear approximation.
