Abstract

Impingement cooling devices for a laser disk include a carrier plate on the front side of which the laser disk can be secured, and a supporting structure, on the front side of which the rear side of the carrier plate is secured. The supporting structure has a plurality of cooling liquid feed lines from which the cooling liquid emerges in the direction of the rear side of the carrier plate and a plurality of cooling liquid return lines. The feed and return lines run parallel to one another in the longitudinal direction of the supporting structure, and the supporting structure includes a plurality of cutouts or the rear side of the carrier plate that are open toward the supporting structure, and the cooling liquid feed lines lead into and the cooling liquid return lines lead away from the plurality of cutouts.
