Construction techniques and commissioning of the Three-Backlink Experiment for the LISA mission
Lea Bischof, Melanie Ast, Jiang Ji Ho-Zhang +10
Designed to detect gravitational waves in the lower-frequency band, the space mission LISA will open a new window to astronomy after its launch in the 2030s. Each LISA spacecraft h…
Demonstrating sub-picometer non-reciprocity levels in the Three-Backlink Experiment for LISA
Jiang Ji Ho-Zhang, Melanie Ast, Lea Bischof +9
The current planned space-based gravitational-wave detectors require a bidirectional optical connection, referred to as Backlink, between two adjacent optical benches to provide a…
Optical suppression of tilt-to-length coupling in the LISA long-arm interferometer
M Chwalla, K Danzmann, M Dovale Álvarez +15
The arm length and the isolation in space enable LISA to probe for signals unattainable on ground, opening a window to the sub-Hz gravitational-wave universe. The coupling of unavo…
Picometer-stable hexagonal optical bench to verify LISA phase extraction linearity and precision
Thomas S. Schwarze, Germán Fernández Barranco, Daniel Penkert +3
The Laser Interferometer Space Antenna (LISA) and its metrology chain have to fulfill stringent performance requirements to enable the space-based detection of gravitational waves.…
