Title (EN) OPTICAL AMPLIFYING DEVICE
(FR) DISPOSITIF D'AMPLIFICATION OPTIQUE
Abstract: front page image
(EN)In an optical amplifying device, an optical beam passes multiple times through a grazing-incidence bounce amplifier, accessing different parts (G1, G2) of the gain region on each transit. This provides improved characteristics in beam quality, with higher power scalability. The multipass configuration can operate as a high gain amplifier device and, with the addition of suitable feedback such as reflectors (M1-M4), as a laser oscillator to provide an optical source.
(FR)L'invention concerne un dispositif d'amplification optique dans lequel un faisceau optique passe à plusieurs reprises à travers un amplificateur à rebond à incidence rasante, accédant à différentes parties (G1, G2) de la région de gain à chaque passage. Il en résulte des caractéristiques améliorées du point de vue de la qualité du faisceau, avec une plus grande variabilité de puissance. Avec cette configuration multipassages, on peut obtenir un dispositif amplificateur à gain élevé et, en ajoutant un moyen de rétroaction adapté tel que des réflecteurs (M1-M4), un oscillateur laser fournissant une source optique.
