提出并实现了一种采用可调谐光纤布拉格光栅（FBG）作为模式限制和波长调谐元件的Ⅰ型和Ⅱ型光纤环级联二次腔宽调谐单纵模（SLM）光纤激光器。由于级联光纤环可以有效地扩展通带间距，使FBG的模式选择更容易，SLM振荡的稳定性可以通过适当地优化II型光纤环中的光耦合器的耦合比，以确保至少一个且只有一个纵向模式在所选择的通带中占主导地位。当光纤环长度设计成使其扩展的通带间距为FBG的3dB带宽的0.5 ~ 1倍时，可以有效地消除相邻通带和主腔模之间的模式竞争，使激光器在宽调谐的同时保持无跳模SLM振荡。
A widely tunable single longitudinal mode (SLM) fiber laser with cascaded Type I and Type II fiber ring secondary cavities, which uses a tunable fiber Bragg grating (FBG) as the mode-restricting and wavelength-tuning element, is proposed and demonstrated. Since the cascaded fiber rings can effectively expand the pass-band spacing to make the mode selection with the FBG easier, the stability of SLM oscillation can be improved by suitably optimizing the coupling ratio of optical couplers in Type II fiber ring to ensure that at least one and only one longitudinal mode dominates in the selected pass-band. When the fiber ring lengths are designed to make their expanded pass-band spacing be a value from 0.5 to 1 times of the 3-dB bandwidth of the FBG, the mode competitions between both neighboring pass-bands and main cavity modes, may be effectively eliminated, making the laser maintain mode-hop-free SLM oscillations while it is widely tuned.
