Characterisation of birefringence inhomogeneity of KAGRA sapphire mirrors from transmitted wavefront error measurements
Haoyu Wang, Yoichi Aso, Matteo Leonardi +7
Cooling down test masses to cryogenic temperatures is a way to reduce the thermal noise of gravitational wave detectors. Crystalline materials are considered the most promising mat…
