Abstract

The results of spectral kinetic studies of several fluoride crystals activated by Yb3+ and Tm3+ ions are presented, and their possible application as cooling elements of optical refrigerators is discussed. Optimum excitation conditions for the laser cooling effect in these crystals are found. The cooling efficiency is established to depend on the degree of order in the active medium.
