Radiation Balanced Lasers (RBL) use cooling from spontaneous emission to offset waste heat generation. This technique offers the potential for very high power operation without thermo-optic distortions or damage. Nevertheless establishing and maintaining radiation balance poses interesting problems for the laser designer. An analysis of RBL’s sensitivity to material losses, intensity variation, and temperature will be presented. This comparison of simulations and experiments is intended to assist in the design of future high power systems.

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.
