摘　　要：设计并实验研究了一种采用Fabry-Perot(F-P)光纤滤波器的2μm波段宽带可调谐全光纤环形激光器,经过放大的1 550nm半导体激光泵浦单模铥-钬共掺光纤(THDF)获得2μm波段宽带增益。实验结果表明,该结构在2μm波段获得了195nm调谐范围的激光输出,线宽0.05nm,边模抑制比66.98dB。整个结构采用铥-钬共掺光纤放大结构,可使输出功率达到瓦级。An all-fiber tunable fiber laser with 2μm band based on Fabry-Perot（F-P）fiber filter was designed and demonstrated experimentally.An amplified 1 550 nm semiconductor laser was adopted to pump a segment of Tm-Ho co-doped fiber（THDF）,and then the optical gain at 2μm band was obtained.The results indicate that the tuning range,linewidth and side-mode suppression ratio of the output laser are 195 nm,0.05 nm and 66.98 dB,respectively.The whole structure adopts the THDF amplification structure,which can achieve output power of watt level.
