Abstract

We explore candidate materials for solid-state laser cooling on electric-dipole allowed transitions that could accelerate refrigeration. We analyze the required external quantum efficiencies and tolerable impurity absorption required to achieve net cooling, and examine limitations imposed by charge transfer and excited state absorption in Yb²⁺:SrF₂, Ce³⁺:LiCAF and Ti³⁺:Al₂O₃.
