Beam angle-locked loop in laser interferometry
Daikang Wei, Christoph Bode, Vitali Müller +2
Maintaining precise beam coalignment is essential in laser interferometry, particularly for interspacecraft missions where angular misalignments introduce tilt-to-length coupling n…
Nested active pointing control for interspacecraft laser interferometry
Daikang Wei, Christoph Bode, Yihao Yan +3
Precise pointing control is a critical requirement for interspacecraft laser interferometry, as angular misalignment introduces measurement noise and even leads to laser link loss.…
Mathematical derivation and verification of the amplitude of LISA's interferometric signals on an ultra-stable interferometer testbed
Alvise Pizzella, Lennart Wissel, Miguel Dovale-Alvarez +5
The Laser Interferometer Space Antenna (LISA) mission aims to detect gravitational waves by interferometrically measuring the change of separation between free-falling test masses…
Experimental Demonstration of an On-Axis Laser Ranging Interferometer for Future Gravity Missions
Daikang Wei, Christoph Bode, Kohei Yamamoto +6
We experimentally demonstrate a novel interferometric architecture for next-generation gravity missions, featuring a laser ranging interferometer (LRI) that enables monoaxial trans…
Experimental end-to-end demonstration of intersatellite absolute ranging for LISA
Kohei Yamamoto, Iouri Bykov, Jan Niklas Reinhardt +10
The Laser Interferometer Space Antenna (LISA) is a gravitational wave detector in space. It relies on a post-processing technique named time-delay interferometry (TDI) to suppress…
