摘要：
An optical gain of 22 dB at 1-535/an is obtained in an Er3+-doped fibre amplifier for a total pump power of 54 mW. The Er3+ doping concentration is 34ppm, and the pumping source is GaAIAs laser diodes at 820 nm. By using an Er3 + fibre with a doping concentration of 390 ppm, the maximum gain is as high as 29-4 dB for a pump power of 83 mW. © 1990, The Institution of Electrical Engineers. All rights reserved.
