| 摘要 |
A system for cooling reflective surfaces of optical mirrors such as laser mirrors is provided, featuring use of multiple small-sized cavities or cells in the mirror body directly behind the reflective surface, through which coolant is caused to flow in short-length paths against the mirror surface between inlet/outlet openings serviced by a single or multiple manifold system, independently servicing each cavity. High coolant flow velocities at regulated rates against various surfaces of the mirror may thus be achieved according to the design requirements without incurring a large pressure drop penalty.
