摘　　要：利用驻波干涉和饱和吸收诱发的自写入光纤光栅的窄带滤波特性及反射波长自适应特性,通过内置可调谐介质薄膜滤波器研制成了可调谐掺铒光纤环形腔单纵模激光器。其有效可调谐波长范围达33nm,在波长连续调谐范围之内均为单纵模输出,激光线宽稳定在2.35KHz以下。Using the very narrow band characteristics of the self-written grating formed in a section of erbium-doped fiber without undergoing pumping by stable standing wave in it, a tunable single-longitudinal -mode erbium-doped fiber ring laser is achieved by inserting a tunable bandpass filter in the resonator.In this configuration the laser is shown to possess 33nm (1532nm-1565nm) tuning range. Its output is single-longitudinal-mode laser in its full wavelength tuning range. And its linewidth is less than 2.35KHz. 
