3D characterization of low optical absorption structures in large crystalline sapphire substrates for gravitational wave detectors
Abstract Very high-quality sapphire substrates are key elements of the cryogenic Japanese gravitational interferometer KAGRA, in which they are used to build the main mirrors, working as the test masses to sense the gravitational waves. To meet the extreme requirements of this system, the sapphire t...
