摘    要:在各类光学系统设计过程中,由于实验系统对于光学器件的透反射率要求不同,需要确定光学器件的透反射率。本文设计了一种对光学器件的透反射率进行精准测量及标定的系统,该系统通过对激光光源进行声光调制,使得激光输出功率的稳定度显著提高,避免了测量时光源不稳定带来的较大误差。实验结果表明,该系统能够稳定光源输出功率,稳定度维持在0.05%/h,甚至更高的水平,满足了光学器件透反射率测量的误差小,精度高等要求。

关 键 词:透反射率  声光调制  激光功率稳定

Abstract: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.
Keywords:transmissivity and reflectivity  acousto-optic modulation  laser power stability
