利用内插窄带双锥光纤滤波器的复合腔共振选模原理和近阈值运转状态下腔内自建可饱和吸收对双向共振模的去耦作用,研制成线宽小于4 MHz的双向、同时、同频、单纵模振荡的全固化掺铒光纤环形激光器,并实现了全光纤环形激光器旋转传感测量。

By the theory of syntonic mode-selecting in the compound ring in which a narrow-band taped fiber filter is embedded and by the uncoupling effect on the bidirectionally operating syntonic mode in the ring of the self-provided saturable absorption under the near threshold operation, a bidirectional, simultaneous, single-mode operating compact Er-doped fiber ring laser with the same frequency is realized, the measurement of rotation sensing of the all fiber ring laser is performed.
