摘要：
A highly efficient Er-doped fibre amplifier pumped by a visible laser diode is reported. Using a 670 nm AlGaInP laser diode as a pump light source and a high NA erbium-doped fibre, the EDFA realised a maximum signal pin of 33 dB at 1535 nm, with a saturated output power of 4 dBm. A maximum pin coefficient of 3.0 dB/mW was achieved for 670 nm laser diode pumping.
