Potential of ytterbium doped silica glass for solid-state optical refrigeration to below 200 K.

Optics Express, 2022
We report on the optical refrigeration of ytterbium doped silica glass by >40 K starting at room temperature, which represents more than a two-fold improvement over the previous state-of-the-art. A spectroscopic investigation of the steady-state and time-
