摘要
本文利用国产半导体激光器泵浦掺Ｙｂ３＋光纤环形激光器获得成功．掺Ｙｂ３＋光纤长３ｍ，与１０５３ｎｍ／９８０ｎｍ波分复用器（ＷＤＭ）构成交叉耦合型全光纤环形腔．总腔长为４ｍ；泵浦波长９８０ｎｍ，激光波长为１０４２．３ｎｍ；斜率效率９．６％，激光阈值低于 ０．５ ｍＷ，利用可调谐钛宝石激光器泵浦，得到该光纤激光器的最佳泵浦波长为９７８ｎｍ．
The Yb-doped fiber ring laser using LD pumping source is reported. The laser system consists of 3 m length fiber and 1053 nm/980 nm WDM which form a crossing all-fiber ring. The length of the cavity is 4 m, pump wavelength 980 nm. The output wavelength 1042.3 nm, slope efficiency 9.6% and threshold smaller than 0.5 mW were obtain. The tunable Ti:shapphire laser is also used as pump source and the optimal pump wavelength 978 nm was observed.
