Birefringence measurements of sapphire test masses for laser interferometer gravitational wave detector

Abstract

We report measurements of the birefringence of a high purity polished sapphire sample to determine the fringe contrast attainable in a laser interferometer gravitational detector. The results show that birefringence-induced losses in the interferometer would be comparable whether sapphire or silica is used.
