Searching systematically for coupling of laser and phase-modulation noise in heterodyne interferometry
Kohei Yamamoto, Olaf Hartwig, Lennart Wissel +3
Heterodyne interferometry for precision science often comes with an optical phase modulation, for example, for intersatellite clock noise transfer for gravitational wave (GW) detec…

Alternative approach to time-delay interferometry with optical frequency comb
Kohei Yamamoto, Hannah Tomio, Charlotte Zehnder +2
Spaceborne gravitational wave observatories, exemplified by the Laser Interferometer Space Antenna (LISA) mission, are designed to remove laser noise and clock noise from interfero…

Ultra-low noise laser and optical frequency comb-based timing system for the Black Hole Explorer (BHEX) mission
Hannah Tomio, Guangning Yang, Holly F. Leopardi +8
In this effort, we demonstrate the performance of a highly stable time reference for the proposed Black Hole Explorer (BHEX) mission, a space-based extension to the Event Horizon T…
