New methods for the rapid cooling of solids with increased efficiency are analyzed and demonstrated experimentally. The advances offered by optical saturation, dipole-allowed transitions, and quantum interference for improved laser cooling of solids are highlighted.
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 radiationbalanced 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.
Laser cooling is an important emerging technology in such areas as the cooling of semiconductors. The book examines and suggests solutions for a range of problems in the development of miniature solid-state laser refrigerators, self-cooling solid-state lasers and optical echo-processors. It begins by looking at the basic theory of laser cooling before considering such topics as self-cooling of active elements of solid-state lasers, laser cooling of solid-state information media of optical echo-processors, and problems of cooling solid-state quantum processors. Laser Cooling of Solids is an important contribution to the development of compact laser-powered cryogenic refrigerators, both for the academic community and those in the microelectronics and other industries.
