Internal Cooling of Fiber and Disc Lasers by Radiation Balancing and other Optical or Phonon Processes

Abstract

This MURI program was conducted by a team comprising of the University of Michigan, Stanford University, Clemson University, and the University of Illinois. This program was dedicated to the demonstration, characterization, and scaling of crystalline, fiber, and disc lasers that are cooled at rates unattainable in the past. Entitled Internal Cooling of Fiber and Disc Lasers by Radiation Balancing and Other Optical and Phonon Processes, this MURI effort has been completed and we report here the highlights from the past five years. Our focus in this MURI program was to advance the technology of optically-cooled materials and demonstrate the cooling of actual operating lasers and amplifiers. We focused on fiber lasers because of their promise for scaling to higher output powers and the need for laser cooling is essential.
