摘要
报道了采用１４７７ｎｍ激光二极管（ＬＤ）泵浦的掺铒光纤放大器的实验结果。研究了放大器的增益和时域特性。对１５２０ｎｍ的信号光，获得了２３ｄＢ的增益，泵浦效率为２．２８ｄＢ／ｍＷ。低频脉冲信号经过放大器后未发生波形畸变。
Experimental results on erbium--doped fiber amplifiers (EDFA) pumped by a 1477 um laser diode are reported. Gain and time characteristics of EDFA are investigated.A maximum gain of 23 dB has been obtained at 1520 um, with pump efficiency being￣ 2. 28 dB/mW.
