Raman Amplifier
The Raman amplifier makes use of stimulated Raman scattering (SRS) within the fiber, which transfers the energy of higher-frequency pump signals to lower-frequency signals. The amplification occurs

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. It is often used in a fiber that carries a signal for a long distance (such as in an undersea cable). Today 27 (1996) 437 Preferential excitation of structurally different VxO y species possible? MeOH partial oxidation on polycryst. Based on the stimulated Raman scattering (SRS) effect, a Raman amplifier uses a transmission fiber as the gain medium to transfer Raman pump power to C-band signals for amplification. The basic principles for SRS are as follows: If weak signal light and strong pump light are transmitted along a.
