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…
Using tunable coherence for reaching micrometer coherence lengths and suppressing stray light in a power-recycled Michelson interferometer
Daniel Voigt, Oliver Gerberding
By reentering into laser interferometers, scattered or stray light introduces non-linear noise. This is a major limitation of precision interferometers as preventing such parasitic…
Scattered light reduction in Sagnac Speed Meters with Tunable Coherence
Leonie Eggers, Daniel Voigt, Oliver Gerberding
Sagnac Speed Meter and ring resonators can be used as high precision instruments, but they are limited in their sensitivity through scattered light causing non-linear noise. Here,…
Tunable coherence laser interferometry: demonstrating 40dB of straylight suppression and compatibility with resonant optical cavities
Daniel Voigt, Leonie Eggers, Katharina-Sophie Isleif +3
A major limitation of laser interferometers using continuous wave lasers are parasitic light fields, such as ghost beams, scattered or stray light, which can cause non-linear noise…
Integrating high-precision and fringe-scale displacement sensing using heterodyne cavity-tracking
Shreevathsa Chalathadka Subrahmanya, Christian Darsow-Fromm, Oliver Gerberding
We present a heterodyne stabilized cavity-based interferometer scheme that can serve as a compact and high-sensitivity displacement sensor with a fringe-scale operating range. The…
