Abstract

We present a theoretical scheme for laser cooling in Tm 3 + -doped oxy-fluoride glass ceramic (GC). Tm 3 + -doped GC has a unique combination of high chemical and mechanical stability related to the oxide glass and low phonon energy of the fluoride nanocrystals, which trap a majority of Tm 3 + ions. This unique property of GC makes it attractive for a number of applications. The effective embedding of rare-earth ions in the crystalline phase with low phonon energy provides high quantum efficiency for the F 4 3 H 6 3 transition in the Tm 3 + ions participating in the cooling cycle.
