摘要：

The reflectance of an ultra-low loss dielectric multilayer coating mirror, which was cooled at 10 K and exposed to 300 K vacuum space, was monitored as the finesse of a Fabry-Perot cavity for two months. The reflectance was measured to decrease with a rate of 0.12(-0.08)(+0.12) ppm per day. Accounting for this result. the cryogenic system for a gravitational wave laser interferometer such as LCGT requires several tens of meters of radiation shields inside its vacuum ducts to keep its optical performance.
