Abstract
An amplifier or laser using the stimulated Raman diffusion effect comprises a light guide (6), and a light pump (10) for producing a pump wave. In order to increase amplification efficiency, the light guide comprises a core structure that includes at least one optically active component that presents an electron transition energy corresponding to a wavelength that is close to the wavelength of the pump wave while nevertheless not being identical thereto. The invention is applicable to optical transmission systems.
Claims11
An amplifier using the stimulated Raman diffusion effect, the amplifier comprising a light guide (6) associated with a light pump (10) for producing a pump wave, the amplifier being characterized in that said light guide comprises a core structure including at least one optically active component presenting an electron energy transition corresponding to a transition wavelength (λt) that is close to the wavelength (λp) of the pump wave but without being identical thereto.
