Abstract
An apparatus is described for cooling the inner circumference of an annular laser window. A cylinder, conductive to heat, is inserted in the central opening of the annular window. Compliant metal wires are used to maintain good thermal contact between the cooling cylinder and the inner circumference of the annular window. A spring compression device is used to maintain constant pressure on the compliant metal wires. The portion of the cooling cylinder outside the window, in the region external to the laser, is slotted. A cooling fluid, typically refrigerated air, is passed through the slots to provide effective heat exchange with the metal cylinder.
