Abstract
A device for cooling a reflecting mirror for reflecting a laser beam is disclosed. A porous member, which permits flow of a cooling fluid through it and has a high thermal conductivity, is held in contact with the reflecting mirror to be cooled. The porous member has a bore coincident with the center of the reflecting surface of the reflecting mirror, at which the laser beam is reflected, and is open on the side opposite the reflecting mirror. Cooling fluid is permitted to flow into the porous member through the bore thereof to improve the heat exchange between the cooling fluid and reflecting mirror, thus improving the cooling capacity and also permitting effective cooling of the reflecting portion of the reflecting mirror, at which the laser beam is reflected.
