OverviewHistoryLaser amplifiersSemiconductor optical amplifierRaman amplifierOptical parametric amplifier21st centuryImplementations

An 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''
