Upconversion cooling of Er-doped low-phonon fluorescent solids
(American Physical Society, 2009-01)
We report on a novel mechanism for laser cooling of fluorescent solids based on infrared-to-visible upconversion often found in rare-earth-doped low-phonon materials. This type of optical cooling presents some advantages ...
