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。
The experimental results of erbium-doped fiber amplifiers with 1477nm laser diode (LD) pumping are reported. The gain and time domain characteristics of the amplifier are studied. For 1520nm signal light, a gain of 23dB is achieved with a pump efficiency of 2.28dB / mW. Low-frequency pulse signal after the amplifier did not waveform distortion.
