Abstract

We present the level of noise induced by Rayleigh-scattered light from sapphire test mass, the limit of scattering loss on build-up power inside the interferometer and finally the tolerable absorption loss in order to meet the specification of the interferometer sensitivity. The results show that the Rayleigh scattering induced noise remains below h similar to 10(-25) Hz(-1/2) and a higher tolerance on the absorption level in sapphire substrate compared with silica substrate.
