Demonstration of length control for a filter cavity with coherent control sidebands
Naoki Aritomi, Yuhang Zhao, Eleonora Capocasa +22
For broadband quantum noise reduction of gravitational-wave detectors, a frequency-dependent squeezed vacuum field realized using a filter cavity is the most promising technique an…
Optical losses as a function of beam position on the mirrors in a 285-m suspended Fabry-Perot cavity
Y. Zhao, M. Vardaro, E. Capocasa +4
Reducing optical losses is crucial for reducing quantum noise in gravitational-wave detectors. Losses are the main source of degradation of the squeezed vacuum. Frequency dependent…
Improving the stability of frequency dependent squeezing with bichromatic control of filter cavity length, alignment and incident beam pointing
Yuhang Zhao, Eleonora Capocasa, Marc Eisenmann +21
Frequency dependent squeezing is the main upgrade for achieving broadband quantum noise reduction in upcoming observation runs of gravitational wave detectors. The proper frequency…
Finite state machine controls for a source of optical squeezed vacuum
Mateusz Bawaj, Valeria Sequino, Catherine Nguyen +8
In this paper we present a software, developed in the distributed control system environment of the Virgo gravitational-wave detector, for the management of a highly automated opti…
