A laser resonator comprises a cylindrical gain medium, a cooling system and a coupling member. The cylindrical gain medium comprises a central axis, an outer side surface, two opposing end faces and a first depression in the outer side surface. The cooling system comprises a cooling jacket disposed around the gain medium that defines a cooling cavity, in which cooling fluid is guided over the side surface of the gain medium. In one embodiment, the cooling jacket comprises a second depression. The coupling member is received within the first and second depressions. Movement of the first depression along the central axis relative to the cooling jacket is restricted by the coupling member.
