Abstract
A method of making a laser mirror substrate having a network of cooling passages in which a plurality of separate plates are injection molded from a mixture of particulate material and binder. The molded plates are combined in a stack to form a unitary body which is then processed to fuse the particulate matter and remove the binder. The individual plates are formed with a pattern of holes which are aligned with the holes in the other plates of the stack to provide passages through the unitary body.
