摘　　要：掺用光纤是一种有源光纤，插入光学谐振腔内可产生激光振荡。我们研制了Ｆ－Ｐ型谐振腔和环形谐振腔，对掺铒光纤激光进行了实验研究。实验中，使用氩离子激光（波长为５１４．５ｎｍ）泵浦，当入纤功率约为３０ｍＷ时，波长为１５３６ｎｍ的红外激光输出为１ｍＷ以上，激光阈值为８ｍＷ，斜率效率大于６％。The Er3+-Doped fiber is a kind of active fiber. It has the function that could amplify optical signal. If it is inserted in an optical resonator, the oscillatory laser will generate.The F-P type resonator and loop type resonator have been developped,and the experiment show that the 1m W IR laser (λ= 1536nm) will be obtained when Ar+ pump-laser(λ= 514.5nm) are applied,and its power in the fiber is 30mW. The IR lasing threshold is 8mW,and the slope efficiency is 6%.
