A new AFOSR MURI program, devoted to the pursuit of cooling solid state lasers internally, is underway and will be described. Comprising research teams from four universities, this program will focus on fiber and disc lasers and the demonstration of optical and/or phonon-based processes capable of maintaining beam quality as power loading of the medium rises. Emphasis will be placed on leveraging novel resonator designs to enhance a targeted optical field-material interaction such that localized cooling occurs within the gain medium. Examples will be given of two systems that are being pursued initially.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
