The idea of cooling a solid-state optical material by simply shining a laser beam onto it may
seem counterintuitive, but this is rapidly becoming a promising technology for future …

This review discusses the progress and ongoing efforts in optical refrigeration. Optical
refrigeration is a process in which phonons are removed from a solid by anti-Stokes …

We present an overview of solid‐state optical refrigeration also known as laser cooling in
solids by fluorescence upconversion. The idea of cooling a solid‐state optical material by …

Laser cooling of solids, sometimes also known as optical refrigeration, is a fast developing
area of optical science, investigating the interaction of light with condensed matter. Apart …

A quantitative description of optical refrigeration in Yb 3+-doped ZBLAN glass in the
presence of transition-metal and OH impurities is presented. The model includes the …

With rising science contents of the engineering research and education, we give examples
of the quest for fundamental understanding of heat transfer at the atomic level. These …

We measured anti-Stokes fluorescence cooling (optical refrigeration) in ytterbium-doped
yttrium aluminum garnet (YAG). Pumping the 2.3% Yb 3+: YAG crystal with 1.8 W of 1030 nm …

We review the field of laser cooling of solids, focusing our attention on the recent advances
in cryogenic cooling of an ytterbium-doped fluoride crystal (Yb^ 3+: YLiF_4). Recently, bulk …

We report a comprehensive model that quantifies analytically and numerically the heat that
can be extracted by anti-Stokes fluorescence (ASF) from a fiber doped with a quasi-two-level …

Herein, the role that point defects have played over the last two decades in realizing solid‐
state laser refrigeration is discussed. A brief introduction to the field of solid‐state laser …
