Abstract
Abstract A cooled laser mirror assembly and mounting structure wherein a laser mirror is mounted in a housing with a coolant flow transfer tube located in two places around the periphery of the laser mirror, one flow transfer tube assembly being for coolant flow into said mirror assembly while the other transfer tube assembly is for directing a fluid flow from said laser mirror assembly. These transfer tube assemblies provide for a coolant flow into and out of the mirror without providing a direct or coolant pressure loading into the mirror. Passage means connects the inner end of the coolant flow transfer tube to passages adjacent the reflecting surface of the mirror. This pressure balance means directs the coolant flow into parallel passages adjacent the reflecting surface of the mirror in the same direction.
