  • In all types of optical system design processes, the transmissivity and reflectivity of optical devices should be determined, because of different requirements in various experiment systems. One system was designed, by which the transmissivity and reflectivity of optical devices could be measured and calibrated with high precision. The laser output power stability was increased significantly by acousto-optic modulation in this system, avoiding larger errors caused by unstable measuring light. It is showed that the system is capable of stablizing light output power from experimental results; the stability is maintained at 0.05%/h, or even higher level, and it meets the requirements of small error and high precision for the measurement of the transmissivity and reflectivity of optical devices.
