本文讨论了光学双稳态光强稳定器特性的物理量——静态稳定度S.据此分析了几种光学双稳态器件在稳态条件下输出光强的稳定性.指出对这种稳定性而言多光束干涉器件优于双光束干涉器件;非线性反馈优于线性反馈,尤以指数反馈为佳.本文还报道了具有指数反馈的电光混合光学双稳态光强稳定器的实验结果,获得了S(?)50的较高稳定度.实验结果与理论计算结果相符.

In this paper a definition of static stability is given and the output power stability of optical bistable devices in the condition of steady operation is discussed. It is pointed out that the multi-beam interference device is better than the two-beam one in static stability and the nonlinear, especially the exponential feedback system is better than the linear one. A laser power stabilizer has been fabricated for the first time by authors using a polarization interference OBD with exponential feedback and a high static stability near 50 haa been obtained. The experimental results are consistent with, the calculated values.
