WebbFiber Optic Raman Amplifiers Govind P. Agrawal, in Guided Wave Optical Components and Devices, 2006 2.1 Raman Gain Spectrum The most important parameter characterizing Raman amplifiers is the Raman gain coefficient γR, which is related to the cross-section of spontaneous Raman scattering [ 7 ]. WebbEr-doped fiber lasers (EDFLs) can be viewed as EDFAs operating in the particular regime where coherent oscillation of ASE occurs due to some feedback means. A standard definition could be the following: EDFLs are used as sources for coherent light signal generation, while EDFAs are used as wave-wave amplifiers for coherent light signal ...
