Effect of heat treatment on mechanical dissipation in TaO coatings
I W Martin, R Bassiri, R Nawrodt +14
Thermal noise arising from mechanical dissipation in dielectric reflective coatings is expected to critically limit the sensitivity of precision measurement systems such as high-re…
Measurements of a low temperature mechanical dissipation peak in a single layer of Ta2O5 doped with TiO2
I Martin, H Armandula, C Comtet +19
Thermal noise arising from mechanical dissipation in oxide coatings is a major limitation to many precision measurement systems, including optical frequency standards, high resolut…
Titania-doped tantala/silica coatings for gravitational-wave detection
Gregory M. Harry, Matthew R. Abernathy, Andres E. Becerra-Toledo +23
Reducing thermal noise from optical coatings is crucial to reaching the required sensitivity in next generation interferometric gravitational-waves detectors. Here we show that add…
Frequency and surface dependence of the mechanical loss in fused silica
Steven D. Penn, Alexander Ageev, Dan Busby +4
We have compiled measurements of the mechanical loss in fused silica from samples spanning a wide range of geometries and resonant frequency in order to model the known variation o…
Very high quality factor measured in annealed fused silica
Alexandr Ageev, Belkis Cabrera Palmer, Antonio De Felice +2
We present the results of quality factor measurements for rod samples made of fused silica. To decrease the dissipation we annealed our samples. The highest quality factor that we…
Thermoelastic dissipation in inhomogeneous media: loss measurements and displacement noise in coated test masses for interferometric gravitational wave detectors
M. M. Fejer, S. Rowan, G. Cagnoli +7
The displacement noise in the test mass mirrors of interferometric gravitational wave detectors is proportional to their elastic dissipation at the observation frequencies. In this…
Mechanical Loss in Tantala/Silica Dielectric Mirror Coatings
Steven D. Penn, Peter H. Sneddon, Helena Armandula +13
Current interferometric gravitational wave detectors use test masses with mirror coatings formed from multiple layers of dielectric materials, most commonly alternating layers of S…
Thermal noise in interferometric gravitational wave detectors due to dielectric optical coatings
Gregory M. Harry, Andri M. Gretarsson, Peter R. Saulson +9
We report on thermal noise from the internal friction of dielectric coatings made from alternating layers of Ta2O5 and SiO2 deposited on fused silica substrates. We present calcula…
High quality factor measured in fused silica
Steven D. Penn, Gregory M. Harry, Andri M. Gretarsson +5
We have measured the mechanical dissipation in a sample of fused silica drawn into a rod. The sample was hung from a multiple-bob suspension, which isolated it from rubbing against…
Pendulum Mode Thermal Noise in Advanced Interferometers: A comparison of Fused Silica Fibers and Ribbons in the Presence of Surface Loss
Andri M. Gretarsson, Sheila Rowan, Geppo Cagnoli +5
The use of fused-silica ribbons as suspensions in gravitational wave interferometers can result in significant improvements in pendulum mode thermal noise. Surface loss sets a lowe…
