Abstract

We constructed a fiber Raman amplifier with an ordinary single-mode fiber in the U-band located on the 1.66μm for the first time. This paper studies the gain characteristics of FRA by using the pump sources with different property and different power. Experiments showed the system amplified steadily when pump power was tens of milliwatt. To the same pump sources, as pump power is increased, the gain of the signal improves obviously. In the case of identical pump powers, FRA' gain is also concerns with the pump source's type and the pump way. When the double-clad Er-Yb codoped fiber laser was used as the pump source, though our 1.66μm fiber Raman amplifier, the signal was amplified effectively and the maximal peak gain reached 5.11dB.
