【摘要】 本文报导了一种基于Bragg型衍射的声光双稳器件。声光晶体由行波场驱动,声场频率则由系统的反馈讯号控制。实验中,观察并记录了输出光强相对输入光强的双稳特性与固定偏置频率的关系,以及在不同输入光强条件下输出光强与偏置频率之间的双稳特性。这些实验结果与理论分析结果一致。更多还原

【Abstract】 An acousto-optical bistable device based on Bragg diffraction is reported in this pa- per. The acousto-optical crystal is driven by a moving sound wave field. The frequency of the sound wave is controlled by the feedback signal of the system. We have observed and recorded the bistable behavior between input and output intensity for different bias frequencies. The bistable behavior between output intensity and the bias frequency for different input intensities were observed and recorded as well. These experimental results agree with the theoretical analysis.更多还原
