Patent ID: 6842473

Claim:
A water getter device ( 10 , 10 ′) for laser amplifiers comprising: a metallic container ( 11 , 11 ′) of cylindrical shape with closed bottom, open upwardly and having a mechanical retainer ( 12 ) at its upper edge; an annular metal member ( 13 ) with an L-shaped profile being inserted in the container and having a height lower than the container, with a cylindrical surface ( 14 ) having an outer diameter slightly smaller than an inner diameter of the container and with a planar surface ( 15 ) facing an inside of the container; a metallic element ( 16 ) being permeable to gases but capable of retaining solid particles, fixed between a planar surface of the metal member with L-shaped profile and said mechanical retainer of the container, which defines a space ( 17 ) with the container bottom and a cylindrical wall of the L-shaped member; and a water getter material ( 18 ) in said space.
