Abstract
An optical refrigeration system that includes a heatlink that is formed by textured crystals that are matched in coefficient of thermal expansion (CTE) to the yttrium lithium fluoride (YLF) cooling crystal, and shaped in geometries that result in very low heat producing losses (HPL). The optical refrigeration system may further include a mirror that is made of a semiconductor-material.
