摘要: CeF3 and PrF3 single crystals are investigated as Faraday rotators for the UV-visible region. Their properties compared with those of industrial standard reference terbium-gallium-garnet (TGG) crystal. In contrast to TGG, exhibits a higher transparency in whole near UV-visible-IR, remarkable figure merit which rapidly increases towards cutoff. case PrF3, extends even shorter wavelengths, analogously its notably UV. These results indicate potential optical isolators UV-visible, where at present there no alternative candidates.
