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…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Demonstrating the velocity response of a table-top EPR Speedmeter
S. L. Kranzhoff, S. L. Danilishin, S. Steinlechner +3
The sensitivity of gravitational-wave interferometers is fundamentally limited by quantum noise, as dictated by the Heisenberg uncertainty principle, due to their continuous positi…
All-polarisation beamsplitters for interferometer applications
S. L. Kranzhoff, Z. Van Ranst, J. De Bolle +9
Optical beamsplitters with similar properties for orthogonal, linear polarisation modes are required for realising polarisation-based speedmeter schemes to reduce back-action noise…
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…
