Application

• An amplifier can boost the (average) power of a laser output to higher levels (→ master oscillator power amplifier = MOPA).
•It can generate extremely high peak powers, particularly in ultrashort pulses, if the stored energy is extracted within a short time.
•It can amplify weak signals before photodetection, and thus reduce the detection noise, unless the added amplifier noise is large.
•In long fiber-optic links for optical fiber communications, the optical power level has to be raised between long sections of fiber before the information is lost in the noise.
