Pagination or Media Count:
Recent experiments and theoretical models relevant to optical cooling of bulk matter are reviewed. A new derivation of the cooling efficiency, accounting both for the escape probability and the saturation intensity, is developed. Applications to an optical refrigerator and a radiation-balanced solid-state laser are considered. An overview is given of results and ideas pertaining to fluorescent cooling of rare earth-doped solids, semiconductors, fluids, and other potential cooling materials, including the basic thermodynamics of the process.
