GaAs/Al0.92Ga0.08 As Crystalline Coatings in Gravitational Wave Detectors
We present defect imaging and birefringence measurements of low thermal-noise GaAs/Al 0 . 92 Ga 0 . 08 As mirror coatings. We also describe nitrogen/phosophorus alloying for strain compensation and growth on offcut germanium to facilitate the use of these coatings in future gravitational wave detectors.
