Optical Regeneration Amplifier

Optical Regeneration Amplifier

A regenerative amplifier is a device which is used for strong amplification of light pulses, usually with ultrashort pulse durations in the picosecond or femtosecond domain (→ ultrafast amplifiers). Multiple passes through the laser gain medium (nearly always a solid-state medium) are achieved by. Optical signals propagating in fiber-optic transmission systems are affected by several effects, namely amplified spontaneous emission (ASE) from optical amplifiers, chromatic dispersion, polarization-mode dispersion, and nonlinear phenomena. It is based on a pulse trapped in a laser resonator, which stays in there until it extracts all of the energy stored in the amplification medium. In-line ampl...
