Abstract
A cooled mirror particularly useful in lasers conducts a cooling fluid through a plurality of parallel paths to impinge on the underface of the reflector member at a plurality of discrete points thereon. The velocity of the cooling fluid is increased such that it issues in the form of a high-velocity jet at each of the discrete impingement points on the underface of the reflector member. The reflector member is thin and flexible and is supported from a rigid base by a plurality of spaced supporting elements in such manner so as to reduce bending of the reflector member by thermal deformation.
