Ultrafast AmplifiersGain SaturationDetrimental Effects of High GainAmplifier NoiseGenerally, amplifiers do not only amplify any intensity or phase noise of the input, but also add some excess noise. This applies not only to laser amplifiers, where excess noise can partly be explained as the effect of spontaneous emission, but also to nonlinear amplifiers. The noise figure e.g. of a fiber amplifier is a measure for how much exces...See more on rp-photonics Wikipedia
Almost any laser active gain medium can be pumped to produce gain for light at the wavelength of a laser made with the same material as its gain medium. Such amplifiers are commonly used to produce high power laser systems. Special types such as regenerative amplifiers and chirped-pulse amplifiers are used to amplify ultrashort pulses.
