Ultrafast AmplifiersGain SaturationDetrimental Effects of High GainAmplifier NoiseAmplifiers of different kinds may also be used for amplifying ultrashort pulses. In some cases, a high repetition rate pulse train is amplified, leading to a high average power while the pulse energy remains moderate. In other cases, a much higher gain is applied to pulses at lower repetition rates, leading to high pulse energies and correspondingl...See more on rp-photonics Wikipedia
