Optical Amplifiers – optical amplification
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

OverviewHistoryLaser amplifiersSemiconductor optical amplifierRaman amplifierOptical parametric amplifier21st centuryImplementationsAn optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from the cavity is suppressed. Optical amplifiers are important in optical communication and laser physics. They are used as optical repeaters in the long distance fiber-optic cables which carry much of the world''
