An 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. La amplifado okazas en tiel nomata gajno, kiu devas esti "pumpita" (t.e., provizita per energio) el ekstera fonto. Plej multaj optikaj amplifiloj estas aŭ optike aŭ elektre pumpitaj.
