摘要：

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. (C) 1998 Elsevier Science B.V.
