Low Thermal Noise TiO2:GeO2 and SiO2 High Reflector Stacks for Gravitational Wave Detectors (JTu4A.2)
Presenter: Aaron Davenport, Colorado State University
Multilayer TiO2:GeO2 alloy and SiO2 coating stacks with >99.999% reflectivity and reduced thermal noise with excellent optical properties are demonstrated. The effect of stepped annealing on the structural properties of the coatings is studied.
