摘要：

A highly efficient Er-doped fibre amplifier pumped by GaAlAs laser diodes is reported. Using a low Er-cluster content fibre with a high numerical aperture, the EDFA attains 39 dB signal gain for double LD pumping and 30 dB for single LD pumping at 1·536μm. A maximum gain coefficient of 1·3dB/mW was achieved at the 0·827μm pump band. © 1990, The Institution of Electrical Engineers. All rights reserved.
