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. However, as laser amplifiers (particularly those based on solid-state gainSee more on rp-photonics Wikipedia
