摘要 提出了一种结构简单的S波段环形腔可调谐光纤激光器,研究了输出功率随激光波长和抽运功率的变化关系以及激光器运转的稳定性。当抽运功率113 mW时,通过调节全光纤可调谐法布里珀罗滤波器,在1482.73~1520.75nm范围内得到了稳定的激光输出,3 dB带宽小于0.03 nm。其中1487.70~1520.75 nm范围内输出功率大于5 dBm,边模抑制比大于60 dB。1499.02 nm处最大输出功率7.11 dBm,输出功率起伏小于0.04 dB。 A tunable S-band fiber ring laser is demonstrated, and the dependence of output power's on the lasing wavelength and the pump power are experimentally researched. Stable output is obtained with the tuning range of 1482.73-1520.75 nm, the 3 dB bandwidth narrower than 0.03 nm and pump power of 113 mW by tuning an all-fiber tunable Fabry-Perot filter. In the range of 1487.70 --1520.75 nm, the output power exceeds 5 dBm and the side mode suppression ratio (SMSR) is larger than 60 dB. A maximal output power of 7. 11 dBm is achieved at 1499.02 nm, together with a fluctuation below 0.04 dB during 900 s.
