Abstract

Optics Physical Sciences Physics Physics, Applied Science & Technology Thermodynamics
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 F-4(3/2) and F-4(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.
