摘　　要：为满足不同频率间隔需求,使用了两个三端口环形器,设计了一种频移间隔可切换的多波长布里渊掺铒光纤激光器(MWBEFL)。该光纤激光器使用两个三端口环形器组成不同环行腔可以分别得到与布里渊泵浦光相隔单倍布里渊频移和双倍布里渊频移的多个激光输出。实验证明,该设计能够实现频移间隔可切换的要求,分别获得26阶、10阶的单倍与双倍布里渊频移激光输出与数十纳米的调谐范围。最后,研究了布里渊泵浦光功率和980nm泵浦光功率对输出激光的影响。In order to meet the requirements of different frequency intervals, this paper proposes a mul- ti-wavelength Brillouin erbium-doped fiber laser（MWBEFL）with switchable frequency shift interval by using two three-port circulators. The paper uses two three-port circulators to form different ring cavities to obtain multiple laser outputs separated from the Brillouin pump laser by a single Brillouin frequency shift interval and a double Brillouin frequency shift interval, respectively. The experiment proves that the design can achieve the requirements of switchable frequency shift interval, and obtain 26 and 10 orders of single and double Brillouin frequency shift laser output and tuning range of tens of nanometers, respectively, and the ef- fects of the Brillouin pump power and the 980nm pump power on the output laser are studied.
