Abstract
本发明涉及一种带有参考光路设计的光纤激光器，其中，所述的光纤激光器包括：种子光源，用于为所述的光纤激光器提供信号光；二合一光路组合器件，与所述的种子光源相连接，用于对输入的信号光进行光路分路以及防止回光处理；以及放大单元，与所述的二合一光路组合器件相连接，用于对输入的信号光进行光放大处理。采用了本发明的该带有参考光路设计的光纤激光器，其通过将参考光纤的分光位置至于非输出端，能够在增加主输出光与参考光的时延的同时，有效抑制非线性效应，增加信号OSNR及输出功率。并且，在无需极低分光比的分路器件、在MON输出端增加衰减或者通过对参考光光功率进行衰减的情况下，均可获得PD及APD采集所需的要求，具有较好的适用性。
