示例性地，预设周期长度光纤光栅可以为周期长度大于1um的光纤光栅，如长周期光纤光栅，具体的预设周期长度可根据实际情况而定，本申请实施例对此不做限定。
在本申请实施例中，泵浦激光器设置有目标中心波长，当泵浦激光器启动后，泵浦激光器就相当于接收到了目标波段光信号发射指令，开始产生波长为目标中心波长的光信号，与此同时，泵浦激光器还会产生部分波长不为目标中心波长的光信号，泵浦激光器将产生的光信号全部传输至第一光纤光栅，即，泵浦激光器将第一光信号传输至第一光纤光栅。
需要说明的是，第一光信号为泵浦激光器产生的光信号。
示例性地，泵浦激光器的目标中心波长为974nm，当泵浦机关器启动后，泵浦机关器就接收到了目标波段光信号的发射指令，产生了波长为974nm的光信号，同时，还产生了部分960-973nm波段范围内的光信号，和部分975-980nm波段范围内的光信号，即，第一光信号就是波长为960-980nm波段范围内的光信号，泵浦激光器发射该波长为960-980nm波段范围内的光信号。
在本申请实施例中，泵浦激光器中设置有谐振腔，当泵浦激光器接收到光信号调整指令时，泵浦激光器的谐振腔就开始谐振，由于该光信号调整指令为泵浦激光器接收到的目标波段的光信号，故泵浦激光器可利用谐振将第二波段光信号转化为目标波段光信号，光信号输出装置就获得到了目标波段光信号，并输出该目标波段光信号。
需要说明的是，目标光信号可以为光信号输出装置输出的目标波段的光信号，如，光信号输出装置设置的目标波段为974-975nm，则光信号输出装置输出的波长为974-975nm的光信号就是目标波段光信号。
需要说明的是，第二波段光信号为目标光纤光栅从第一波段光信号中，筛选出来的、除目标波段光信号外的光信号。
示例性地，目标波段光信号的波长范围为974-975nm，第二波段光信号的波长范围为976-978nm，当泵浦激光器接收到波长范围为974-975nm的光信号的调整指令时，泵浦激光器就产生谐振，将波长范围为976-978nm的光信号转化为波长范围为974-975nm的光信号，此时，光信号输出装置就获得到了波长范围为974-975nm的目标波段光信号，并输出该目标波段光信号。
在本申请实施例中，第一光纤光栅包括光栅反射率，当第一光纤光栅接收到泵浦激光器发射的第一光信号时，第一光纤光栅从该第一光信号中筛选第一波段光信号，并将第一波段光信号中符合该光栅反射率的光信号返回至泵浦激光器，使得泵浦激光器的谐振腔开始谐振，将第一光信号中的除第一波段光信号外的光信号，转化为第一波段光信号，该第一波段光信号的中心波长与目标波段光信号的目标波长相同，从而筛选出第一波段光信号并传输至目标光纤光栅。
需要说明的是，第一波段光信号为第一光纤光栅从第一光信号中筛选出的光信号，第一波段光信号的中心波长为目标波段光信号的目标波长，且第一波段光信号的波段范围小于第一光信号的波段范围。
在本申请实施例中，第一光纤光栅可以为普通光纤光栅，具体的可根据实际情况而定，本申请实施例对此不做限定。

可选的，所述预设周期光纤光栅为具有单方向光信号传输特征的光纤光栅。
在本申请实施例中，预设周期光纤光栅为同向传播的纤芯基模与包层模的耦合型光纤光栅，因此，预设周期光纤光栅中的光信号传输方向为从预设周期光纤光栅的输入端传输至输出端。
可以理解的是，通过在第一光纤光栅后设置预设角度光纤光栅或者是预设周期光纤光栅，使得预设角度光纤光栅或者是预设周期光纤光栅在筛选出目标波段光信号的同时，利用泵浦激光器的谐振操作将第二波段光信号也转化为目标波段光信号，从而得到高质量的目标波段光信号，提高了泵浦激光器输出的目标中心波长的光的质量。
