本文报道了一台70 nm宽的准连续可调谐单频掺铒光纤(EDF)激光器的实验结果，该激光器在1510-1580 nm之间产生单纵模振荡，输出功率为0.5 mW，调谐步长约为25 MHz。该腔包括三个可调谐带通滤波器：基于体栅的可调谐带通滤波器、光纤环形腔滤光器和由未抽运的EDF产生的自动跟踪饱和吸收感生光栅滤波器。该激光器的频率漂移为100 MHz，信源自发辐射比大于60分贝。
In this letter, we report on experimental results on a 70-nm-wide quasi-continuously tunable single-frequency erbium-doped fiber (EDF) laser, in which the laser produced a single-longitudinal mode oscillation between 1510-1580 nm, an output power of 0.5 mW, and a tuning step of about 25 MHz. The cavity incorporates three tunable bandpass filters (TBFs): a bulk-grating-based TBF, a fiber-ring-cavity filter, and an autotracking saturable absorption-induced grating filter generated by an unpumped EDF. This laser had a frequency drift of 100 MHz and a signal-to-source spontaneous emission ratio higher than 60 dB.
