摘　　要：报道了采用光学铌酸锂晶体作声光介质，氧化锌压电薄膜相位阵列换能器制作的高频宽带声光布喇格器件。达到的主要结果是：中心频率２．２５ＧＨｚ，瞬时带宽０．７５ＧＨｚ，频率分辨率８ＭＨｚ，工作激光波长６３２．８ｎｍ。Acoustooptic Bragg devices using optical LiNbO 3 crystal as the acoustooptic media and phased array ZnO piezoelectric film transducers ars reported in this paper. The devices have high center operation frequency and wide bandwidth. The results show that their operational wavelength is 632.8 nm(He Ne laser),center frequency is 2.25 GHz,instantaneous bandwidth 0.75 GHz,and frequency resolution 8 MHz.
