Abstract

The amplification of an optical signal in an erbium-and ytterbium-doped fiber saturation-mode amplifier is considered. Analytical distributions of the inverse population, pump power, and signal intensity along an active light guide are derived. Spectral dependences of the saturation power and amplification threshold are obtained for different mode sizes of the radiation and ytterbium-to-erbium active ion ratios. The optimal active-fiber length is calculated.
