Raman scattering optical amplifier

摘要

The amplifier has an optical fiber (6) associated to an optical pump (10) for producing a pump wave. The optical fiber comprises of a core structure which includes optically active components e.g. lanthanide ions, presenting an electronic energy transition corresponding to a transition wavelength which is close and unidentical to the wavelength of the pump wave. An independent claim is also included for a laser source comprising an optical amplifier with Raman effect disposed inside a resonant cavity.
