Abstract

L'invention concerne un élément d'amplification laser (100) comportant : - un milieu amplificateur (20), présentant une face avant (21) et une face arrière (22); - un élément de refroidissement comportant au moins un système de refroidissement (40), situé du côté de la face arrière (22) du milieu amplificateur ; et - un hublot (70), situé du côté de la face avant (21) du milieu amplificateur, recouvrant à la fois la face avant (21) du milieu amplificateur et une surface d'échanges thermiques périphérique (47) de l'élément de refroidissement. L'invention permet d'augmenter une surface d'échanges thermiques entre le milieu amplificateur et l'élément de refroidissement. On peut ainsi utiliser de plus grandes puissances de pompage, et donc augmenter une puissance d'émission laser.The invention relates to a laser amplification element (100) comprising: - an amplifying medium (20), having a front face (21) and a rear face (22); - a cooling element comprising at least one cooling system (40), located on the side of the rear face (22) of the amplifying medium; and - a window (70), located on the side of the front face (21) of the amplifying medium, covering both the front face (21) of the amplifying medium and a peripheral heat exchange surface (47) of the element cooling. The invention makes it possible to increase a heat exchange surface between the amplifying medium and the cooling element. It is thus possible to use greater pumping powers, and therefore to increase a laser emission power.
