Abstract

The first experimental demonstration of local internal and bulk optical cooling in samples of Nd-doped KPb₂Cl₅ crystals and Nd-doped KPb₂Cl₅ nanocrystalline powders upon laser excitation between the ⁴F_3/2 and ⁴F_5/2 manifolds is reported. The possibility of controlling the dynamics of the bulk optical cooling process by adequately tuning the excitation wavelength is also demonstrated.
