Abstract
A dual-stage doped fiber amplifier is provided which utilizes a single pump laser and a passive power splitter to pump both amplifier stages. The passive splitter couples a first portion of the power output of the single pump laser to a first stage amplifier and a second portion of the pump power to the second stage. In this manner, the performance characteristics of the amplifier can be controlled by utilizing a single pump source.
