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．
In this paper, the domestic semiconductor laser pump doped Yb3 + fiber ring laser to be successful. Yb3 + doped fiber length 3m, and 1053nm / 980nm wavelength division multiplexer (WDM) form cross-coupling all-fiber annular cavity. The total cavity length is 4 m; the pump wavelength is 980 nm, the laser wavelength is 1042.3 nm; the slope efficiency is 9.6% and the laser threshold is lower than 0.5 mW. The best fiber laser is obtained by pumping with a tunable Ti: sapphire laser The pump wavelength is 978 nm.
