Description
Silicon with AlGaAs coatings is a promising technology for future gravitational wave detectors. There are several unanswered questions that we aim to probe in experiments at the University of Western Australia and the High Optical Power Facility. In this presentation we present measured results of birefringence in float zone Silicon test-masses and beam-splitters. We present the characterisation plan for 10cm diameter Silicon mirrors with AlGaAs coatings. We explain the design and progress that has been made towards the cryogenic Silicon suspended coupled cavity. And describe some of the major challenges we have faces along the way.
