Raman amplification - Raman amplification (pronounced /rʌmɑn/) is based on the Stimulated Raman Scattering (SRS) phenomenon, when a lower frequency 'signal' photon induces the inelastic scattering of a higher-frequency 'pump' photon in a nonlinear optical medium. As a result of this, another 'signal' photon is produced, with the surplus energy resonantly passed to the vibrational states of the nonlinear medium.

Amplification - *Generally, amplification is a basic process sometimes seen in nature, and often used in processes which involve a signal which must be made stronger. See amplifier.

Signal processing - Signal processing is the processing, amplification and interpretation of signals and deals with the analysis and manipulation of signals.

Transistor - The transistor is a solid state semiconductor device which can be used for amplification, switching, voltage stabilization, signal modulation and many other functions. It acts as a variable valve which, based on its input voltage, controls the current it draws from a connected voltage source.
