Raman amplifiers are optical amplifiers based on Raman gain. They are often operated with light pulses, although continuous-wave operation is also possible.
Raman amplification /ˈrɑːmən/ is a way of increasing the signal strength in an optical fiber. It is often used in a fiber that carries a signal for a long distance (such as in an undersea cable). Technically, it works by stimulating Raman scattering, in which a lower frequency ''signal'' photon induces inelastic scattering of a higher-frequency ''pump'' photon in an optical medium in the nonlinear regime. As a result, another ''signal'' photon is produced, with the surplus energy resonantly passed to the vibrational states of the

This Raman amplifiers buying guide provides technical background, comparison of major types, selection criteria, and an overview of suppliers.
More than 200 W output power from a Raman amplifier is presented. 1 W seed signal (wavelength 1125 nm) was generated in a Raman oscillator and fed into the Raman Amplifier subsequently.
The experimental results demonstrate a 200-nm bandwidth from a single fiber-optical amplifier and also verify that the influence of the Raman effect is relatively small, as predicted by the theory. Index
