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…
