Progress in the measurement and reduction of thermal noise in optical coatings for gravitational-wave detectors
Progress in the measurement and reduction of thermal noise in optical coatings for gravitational-wave detectors
Coating thermal noise is a fundamental limit for experiments involving optical and quantum transducers. We report on the latest research activity on low-noise coatings at the Laboratoire des Matériaux Avancés, from updated values for the current Ta2O5, Ta2O5-TiO2 and SiO2 coatings of the Advanced LIGO, Advanced Virgo and KAGRA detectors …
