Abstract
A solid-state optical refrigerator for cryogenic cooling of a payload, the solid-state optical refrigerator including a laser cooling crystal including a first material and a dopant material; a thermal link including a second material, the thermal link being bonded to the laser cooling crystal and the thermal link being configured to be thermally linked to the payload to transfer heat conductively from the payload to the laser cooling crystal via the thermal link; and a vacuum chamber housing the laser cooling crystal and the thermal link, the vacuum chamber and thermal link having a combination of shape and coating such that laser and fluorescence light reflected off a wall of the vacuum chamber and laser and fluorescence light propagating within the thermal link are not incident on the payload.
