Abstract

A laser disk module includes a lasing element including an active gain medium, the lasing element including opposite top and bottom end surfaces, and a heat transfer element adjacent the bottom end surface, the heat transfer element including a ceramic material that defines a plurality of cooling structures. The heat transfer element is configured to transfer heat generated in the lasing element to a coolant in contact with the heat transfer element in the plurality of cooling structures during operation of the laser disk module.
