NANOSTRUCTURES: Optical absorption in CaF2 nanoceramics
Abstract
The optical characteristics of two Russian-made CaF2 ceramic samples are compared to those of single-crystal CaF2. The results indicate that the ceramic possesses high optical quality and a small absorption coefficient (~10-3 cm-1 at a wavelength of 1.07 μm) and is suitable as a material for optical components. Experimental evidence is presented for spatial modulation of the thermally induced depolarisation in the ceramic.
