Abrégé
(EN)
The present invention is an amplifier for amplifying an optical signal (12). The signal to be amplified (12) passes into and then from a first optical manipulator. The first manipulator is at least one or more collimators and/or concentrators. The amplifier includes an input pump (14) which produces pump light (15) overlapping the optical signal as the signal passes from the first manipulator. The amplifier further includes a plurality of ion-doped crystalline hosts (18) to be excited by the pump light and impinged by the signal. Finally the signal passes through a second manipulator, which is also one or more collimators and/or concentrators, and exits the amplifier.

La présente invention concerne un amplificateur destiné à l'amplification d'un signal optique. Le signal à amplifier pénètre et ensuite sort d'un premier manipulateur optique. Le premier manipulateur consiste en au moins un ou des collimateurs et/ou concentrateurs. L'amplificateur comporte une pompe d'entrée qui produit une lumière de pompage recouvrant le signal optique lors du passage du signal hors du premier manipulateur. L'amplificateur comporte en outre une pluralité d'hôtes cristallins dopés aux ions pour leur excitation par la lumière de pompage et leur impaction par le signal. Enfin le signal traverse dans un deuxième manipulateur, qui est consiste également en un ou des collimateurs/concentrateurs, et sort de l'amplificateur.
