摘　　要：报道采用一级束控的声光偏转器.其带宽和衍射效率均明显优于传统器件结构的实验结果.它是高频宽带声光偏转器件发展采取的合理途径.The acoustooptic deflectors using first order beam steering transducers are reported in this paper. The experimental results show that.their bandwidth and diffraction efficiency are obviously larger than those of conventional devices,and the method of first order steering is a suitable way for developing acoustooptic deflectors with high frequency and wide bandwidth.

关 键 词：声光偏转器 束控 带宽 衍射效率
