| الوصف: | Laser cooling of solids currently has a temperature floor of 50 - 100 K. We propose a method that could overcome this using defects, such as diamond color centers, with narrow electronic manifolds and bright optical transitions. It exploits the dressed states formed in strong fields which extend the set of phonon transitions and have tunable energies. This allows an enhancement of the cooling power and diminishes the effect of inhomogeneous broadening. We demonstrate these effects theoretically for the silicon-vacancy and the germanium-vacancy, and discuss the role of background absorption, phonon-assisted emission, and non-radiative decay. Comment: 11 pages, 7 figures. v2: Improved discussion of competing heating processes and phonon-assisted decay. New supplemental material with summary of methods, analysis of validity of Born-Markov approach, results for the germanium-vacancy. v3: Simplified presentation of method in main text |
