Abstract
A theoretical model of optical amplification in a praseodymium-doped fiber amplifier that is optically pumped at about 1 μm and amplifies signals at about 1.3 μm is presented. The variation of gain with respect to fiber length in both small-signal and saturated operation is reported, and the adverse influences of a lower-level bottleneck and a multiphonon cascade from the pump band are discussed
