Widefield Spectroscopic Telescope (WST): coating strategy to achieve high optical throughput
Benoit Sassolas, Matthieu Coulon, Christophe Michel +4
The Wide-field Spectroscopic Telescope (WST) is a 12-m class facility designed for simultaneous wide-field multi-object and integral-field spectroscopy across 370-1600 nm, targetin…
A Systematic Error in the Internal Friction Measurement of Coatings for Gravitational Waves Detectors
Alex Amato, Diana Lumaca, Elisabetta Cesarini +9
Low internal friction coatings are key components of advanced technologies such as optical atomic clocks and high-finesse optical cavity and often lie at the forefront of the most…
Effects of mixing and annealing on the optical and mechanical properties of TiO:TaO amorphous coatings
Alex Amato, Michele Magnozzi, Nikita Shcheblanov +7
Amorphous mixed titania-tantala coatings are key components of Bragg reflectors in the gravitational wave detectors (GWDs). Attaining the lowest possible values of optical absorpti…
Point defects in IBS coating for very low loss mirrors
Sihem Sayah, Benoît Sassolas, Jérôme Degallaix +4
High reflective coatings are used in many physics experiments. Despite the high quality of the opticalcoating, the performances of the mirrors is altered by the scattered light ind…
Amorphous optical coatings of present gravitational-wave interferometers
Massimo Granata, Alex Amato, Laurent Balzarini +10
We report on the results of an extensive campaign of optical and mechanical characterization of the ion-beam sputtered oxide layers (TaO, TiO, TaO-TiO, SiO$…
Observation of a Correlation Between Internal friction and Urbach Energy in Amorphous Oxides Thin Films
Alex Amato, Silvana Terreni, Massimo Granata +5
We have investigated by spectroscopic ellipsometry (SE, 190-1700 nm) the optical properties of uniform, amorphous thin films of Ta2O5 and Nb2O5 as deposited and after annealing, an…
