Abstract
A laser window is formed of spaced transparent strips with a high total surface area that lends itself to cooling by conduction heat transfer to metal channels between the strips. The metal channels carry either a fast flowing refrigerant or heat-pipe wick and fluid. One or both sides of the metal cooling channels can act as mirrors.
Claims6
A window for a laser to facilitate the extraction of absorbed, injurious laser light energy from the window, the assembly including,
- (a) a plurality of spaced mirrors which reflect laser light emanating from the interior of the laser back to the interior of the laser,
- (b) a plurality of spaced strips which transmit laser light through the interior of the laser to outside of the laser,
- (c) each said strip positioned between and contacting a portion of adjacent mirrors and being in heat conducting relation thereto,
- (d) means for continually cooling each of said mirrors,
- (e) whereby heat energy absorbed by the strips as laser light passes therethrough at least partially passes by conduction to the mirrors from whence it is carried away by the said means for cooling the mirrors.
