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 4F3/2 and 4F5/2 manifolds is reported. The possibility of controlling the dynamics of the bulk optical cooling process by adequately tuning the excitation wavelength is also demonstrated.
