Optical refrigeration in Tm- and Ho-doped crystals is investigated, and their external quantum efficiency, background absorption, and minimum achievable temperatures are reported. Potential of these crystals for mid-IR cryocoolers and radiation balanced lasers are discussed.

Abstract
Optical refrigeration in Tm- and Ho-doped crystals is investigated, and their external quantum efficiency, background absorption, and minimum achievable temperatures are reported. Potential of these crystals for mid-IR cryocoolers and radiation balanced lasers are discussed.File in questo prodotto:
