Optical amplifier - Wikipedia
WEBAn 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 – optical amplification - RP Photonics
WEBAn optical amplifier is a device which receives some input signal light and generates an output signal with higher optical power. Typically, inputs and outputs are laser beams (very rarely other types of light beams), either propagating as Gaussian beams in free space or in a fiber.

WEBDefinition: Optical amplifier is a device used in an optical communication system to directly amplify (boost) optical data signal without changing it into its electrical form. By making use of Optical amplifiers in optical fiber communication, the optical integrity of the whole system is retained.
Semiconductor Optical Amplifiers – SOA - RP Photonics
WEBA semiconductor optical amplifier is an optical amplifier based on a semiconductor gain medium. It is essentially like a fiber-coupled laser diode where the end mirrors have been replaced with anti-reflection coatings; a tilted waveguide can be used to further reduce the end reflectivities.
