Observation of Optical Refrigeration in Tm3+:BaY2F8

Not Accessible

Your library or personal account may give you access

Abstract

We report the first experimental demonstration of laser cooling with thulium-doped BaY2F8. Cooling by ~ 1.5 K below ambient temperature is obtained at λ = 1.902 µm in a single pass geometry.
