The gain characterization of photonic crystal fiber amplifier is theoretically and experimentally studied by using reverse pumping technique. The gain curves for different pumping powers and different signal lights are obtained experimentally. When the power of the probe light is 6W and the pump power is 160Wthe output power up to 104Whas been achieved eventually. It is found in the experiment that when the pump power is increased over a certain valuethe output of the amplifier evolves into the unstable statewhich in turn degrades the system performance.
