Abstract

Based on the fundamental theory of quantum amplifier

the phenomena of excited state absorption （ ESA ） in Erbium-Doped Fiber Amplifier （ EDFA ） is studied in this paper. The expression of the optimum Er3 + -doped fiber length pumped with 800nm LD is obtained where strong ESA exists. The calculated result using typical parameters of Er3 + -doped fiber is found to be in excellent agreement with the result of the experiment. Finally.a method of realising high-gain LD pumped EDFA is proposed.
