    摘要: A fiber optic amplifier is disclosed utilizing a doped fiber to provide amplification through stimulated emission. The doped fiber is simultaneously pumped by multiple pump lasers generating optical waves of differing wavelengths. The optical waves from the lasers are combined using a wavelength division multiplexer before introduction into the doped fiber. The use of multiple pump lasers decreases the power requirements of each laser, reduces the cost of the amplifier, and increases reliability without compromising the gain of the amplifier.
