Raman amplification
Today, Optical fiber is most often used as the nonlinear medium for stimulated Raman scattering for telecom purposes. In this case it has a resonance frequency downshift of ~11 THz (corresponding to

How a Raman Amplifier Boosts Optical Signals
Discrete Raman amplifiers, conversely, use a dedicated, relatively short spool of fiber, sometimes a high-nonlinearity fiber, contained within a compact module. This setup acts as a lumped amplifier,
