摘要: 将He-Ne激光和外电场同时作用在Fabry-Perot腔内的向列相液晶(8CB,5CB)上,实现光学双稳态。获得双稳的最大输出光强,开启光强与外电场强度关系,同时首次获得双稳特性与电场频率的关系。Abstract: This paper repots that optical bistability is achieved When both He-Ne laser and external electric field act simultaneously on nematic phase liquid crystals(8CB,5CB)in F-P cavity. The relationships between maximum light Intensity,switch off light inten sity and electric voltage were obtained.
