介绍了间接式光纤声光移频器的设计、结构和研究制作。在１．３μｍ光波长下，用单模光纤耦合，获得了移频频率５０ＭＨｚ±０．１ＭＨｚ、频率稳定度优于１０－５／ｈ、插入损耗－１０．９８ｄＢ和性能稳定的实验结果
The design, structure and research of indirect optical fiber acousto-optic frequency shifter are introduced. At the wavelength of 1.3μm, single-mode optical fiber was used to couple the experimental results of 50MHz ± 0.1MHz frequency shift, better than 10-5 / h frequency stability, -10.98dB insertion loss and stable performance
