Claim Text:
1. A laser resonator comprising: a gain medium having a central axis, an outer surface, and two opposing end faces; a cooling jacket including an inner surface and two opposing end portions, the cooling jacket being disposed around the gain medium to define a cooling cavity that receives radiation from the gain medium and guides a cooling fluid over the outer surface of the gain medium; a first depression in the outer surface of the gain medium that is located in the cooling cavity, between the two opposing end faces of the gain medium; a second depression in the inner surface of the cooling jacket that is located in the cooling cavity, between the two opposing end portions of the cooling jacket; and a coupling member received in the cooling cavity within the first and second depressions to restrict movement of the first depression along the central axis relative to the second depression, wherein the coupling member is exposed to the radiation in the cooling cavity and the two opposing end faces of the gain medium are movable along the central axis relative to the two opposing end portions of the cooling jacket.
