Commissioning of the tuned DC readout at GEO 600

Degallaix, J.; Grote, Hartmut; Prijatelj, M.; Hewitson, M.; Hild, S.; Affeldt, Christoph; Freise, A.; Leong, J.; Lück, Harald; Strain, Kenneth A.; Wittel, H.; Willke, Benno; Danzmann, Karsten (Bristol : IOP Publishing Ltd., 2010)

Recent experimental results from GEO600 operating with a DC readout and a tuned signal recycling cavity are reported. Compared to the S5/Astrowatch setup, two major changes in the configuration have been implemented: the ...
Coupling of relative intensity noise and pathlength noise to the length measurement in the optical metrology system of LISA Pathfinder

Wittchen, A.; et al.; LPF Collaboration (Bristol : Institute of Physics Publishing, 2017)

LISA Pathfinder is a technology demonstration mission for the space-based gravitational wave observatory, LISA. It demonstrated that the performance requirements for the interferometric measurement of two test masses in ...
Relative-Intensity-Noise Coupling in Heterodyne Interferometers

Wissel, Lennart; Wittchen, Andreas; Schwarze, Thomas S.; Hewitson, Martin; Heinzel, Gerhard; Halloin, Hubert (College Park, Md. [u.a.] : American Physical Society, 2022)

Laser interferometers are the core measurement tool in gravitational wave observatories. An important factor that can limit the performance is the relative power instability of the laser, a problem often called relative ...
Tracking Length and Differential-Wavefront-Sensing Signals from Quadrant Photodiodes in Heterodyne Interferometers with Digital Phase-Locked-Loop Readout

Heinzel, Gerhard; Álvarez, Miguel Dovale; Pizzella, Alvise; Brause, Nils; Delgado, Juan José Esteban (College Park, MD : American Physical Society, 2020)

We propose a method to track signals from quadrant photodiodes (QPDs) in heterodyne laser interferometers that employ digital phase-locked loops for phase readout. Instead of separately tracking the four segments from the ...
