A method is described for determining the reflection coefficients of high-density mirrors, based on the use of a mode-locked laser and a sensitive detector with a fast time resolution. The laser light is transmitted through an optical resonator formed by the investigated mirrors. The measured delay in the decay of a light pulse gives the damping time of the optical resonator. This is related to its Q factor determined by the reflection coefficients of its mirrors.
