摘　　要：研究了光纤声光耦合环形腔独特的谐振特性。结果表明利用光纤声光耦合器的移频与滤波特性 ,可研制成一种全新结构的光纤声光耦合环形谐振腔。从理论和实验上证明了 :基于腔内累积声光移频分量的多光束干涉 ,光纤声光耦合环形谐振腔可将注入的连续激光将转换为脉冲列输出。The characteristics of fiber acousto-optic coupled ring resonators were studied. It is found that a novel acousto-optic coupled ring resonator can be got for the frequency-shift and filtering characteristics of the acoustooptic fiber coupler. Theory and experiments have demonstrated that such a resonator has a unique feature that it can convert continuous laser to pulse train caused by the interference of multiple-beams with accumulative shift frequencies in the fiber loop.
