Title
(EN) A METHOD AND A SYSTEM FOR GENERATING A RAMAN SECOND STOKES LIGHT TO A SOURCE LIGHT
(FR) PROCÉDÉ ET SYSTÈME POUR GÉNÉRER UNE SECONDE LUMIÈRE DE STOKES DE RAMAN SUR UNE LUMIÈRE DE SOURCE
Abstract
(EN) A method and system for generating a Raman second Stokes light to a source light comprising generating a Raman first Stokes light from the source light by a Raman interaction in a nonlinear optical medium disposed in an optical resonator, and resonating the Raman first Stokes light in the optical resonator; generating a seed light at the frequency of the Raman second Stokes light from the source light and the Raman first Stokes light by a four wave mixing process which is not phase matched in the nonlinear medium; amplifying the seed light by transferring power from the first Stokes light resonating in the optical resonator to the seed light using a Raman amplification process in the nonlinear medium; and extracting from the optical resonator a majority of the power of the seed light so amplified.
(FR) L’invention porte sur un procédé et un système pour générer une seconde lumière de Stokes de Raman sur une lumière de source, comprenant la génération d’une première lumière de Stokes de Raman à partir de la lumière de source par une interaction de Raman dans un support optique non linéaire disposé dans un résonateur optique, et la résonance de la première lumière de Stokes de Raman dans le résonateur optique ; la génération d’une lumière de graine à la fréquence de la seconde lumière de Stokes de Raman à partir de la lumière de source et de la première lumière de Stokes de Raman par un processus de mélange de quatre ondes qui n’est pas adapté en phase dans le support non linéaire ; l’amplification de la lumière de graine par transfert d’une puissance depuis la première lumière de Stokes résonant dans le résonateur optique vers la lumière de graine en utilisant un processus d’amplification de Raman dans le support non linéaire ; et l’extraction à partir du résonateur optique d’une majorité de la puissance de la lumière de graine ainsi amplifiée.
