Almost any laser can be to produce for light at the wavelength of a laser made with the same material as its gain medium.
Why do we need Optical Amplifiers? Typical fiber loss around 1.5 μm is ~0.2 dB/km. Aer traveling ~100 km, signals are aenuated by ~20 dB, They need to be amplified or signal‐to‐noise ra,o (SNR) of

OverviewLaser amplifiersHistorySemiconductor optical amplifierRaman amplifierOptical parametric amplifier21st centuryImplementations
Almost any laser active gain medium can be pumped to produce gain for light at the wavelength of a laser made with the same material as its gain medium. Such amplifiers are commonly used to produce high power laser systems. Special types such as regenerative amplifiers and chirped-pulse amplifiers are used to amplify ultrashort pulses.
