Ultrafast AmplifiersGain SaturationDetrimental Effects of High GainAmplifier NoiseFor high values of the input light intensity or fluence, the amplification factor of a gain medium saturates, i.e., is reduced (→ gain saturation). This is a natural consequence of the fact that an amplifier cannot add arbitrary levels of energy or power to an input signal.
