An All-Solid Cryocooler to 100K Based on Optical Refrigeration in Yb:YLF Crystals
Abstract
Optical refrigeration has become the only solid-state refrigeration mechanism capable of reaching cryogenic temperatures. With the coldest solid-state temperatures (T >185K from 300K) achievable by optical refrigeration, it is now timely to apply this technology to cryogenic devices. Along with thermal management and pump absorption, this work addresses the most key engineering challenge of transferring cooling power to the payload while efficiently rejecting optical waste-heat fluorescence. We discuss our optimized design of such a thermal link, which shows excellent performance in optical rejection and thermal properties.
