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…

Effect of Optical Coating and Surface Treatments on Mechanical Loss in Fused Silica
Andri M. Gretarsson, Gregory M. Harry, Steven D. Penn +3
We report on the mechanical loss in fused silica samples with various surface treatments and compare them with samples having an optical coating. Mild surface treatments such as wa…
