A method for controlling an optical amplifier is disclosed. The illustrative method includes inputting a set-point to a controller; receiving a portion of an input signal; receiving a portion of an output signal from a first amplifier stage; receiving a portion of an output signal from an attenuation stage; receiving a portion of an output signal from a second amplifier stage and adjusting the first amplifier stage, the second amplifier stage and the attenuation stage based on the received portions to substantially maintain the set-point. An optical amplifier includes a controller which receives a portion of an input signal, a portion of an output signal from a first amplifier stage, a portion of an output signal from an attenuations stage, and a portion of an output signal from a second amplifier stage. The controller adjusts the first amplifier stage, the attenuation stage, and the second amplifier stage based on the received portions of the signals.
