Paper Abstract

Cavity Ring-Down Spectroscopy (CRDS) is a highly sensitive loss measurement technique. It was used for quantitative diagnostics of molecular species. In our experiment CRDS has been applied for measuring the reflectivities of optical mirrors. An experimental system has been established. The reflectivities of a pair of cavity mirrors and of a 22.5° optical mirror have been measured. The reflectivities of the cavity mirrors are (99.925±0.001) % and that of the 22.5° mirror is (99.992±0.003) %° The measurement error was as low as 0.001%.
