摘　　要：用波分复用 (WDM)光栅串作环形腔端镜 ,调节F P滤波器透过的共振波长 ,实现对应光栅波长的稳定激光输出 ,其斜率效率在 0 0 9左右 ,实验表明光栅反射率以及所处波长处的增益影响激光阈值的大小。用全反镜替代光栅串 ,在 15 30～ 15 75nm范围内可对输出波长进行连续调节。By controlling the transmitted resonant wavelength of a Fabry-Perot filter, stable single frequency laser output which corresponding to one of the reflected wavelength of a five fiber Bragg grating wavelength division multiplexing (WDM) array acted as selective reflector was obtained and with slope efficiency of ～0.09. Experiment demonstrated that the lasing threshold is related to the grating′s reflectivity and the gain of the erbium-doped fiber at the working wavelength. Continuous tuning within the range of 1530 nm to 1575 nm was achieved with the grating array replaced by a board band reflective mirror.
