Abstract
(EN)
The problem addressed by the invention lies in providing a Faraday rotor, optical isolator and optical processing equipment having transmissivity greater than TGG, capable of being scaled up in size and having a high performance index at a wavelength in the visible wavelength region, in particular 400 nm or less. A Faraday rotor characterised in that it comprises as a main component a fluoride compound represented by the following general formula (1) or (2): RE1F3-x ・・・(1) LiRE2F4-x・・・(2) where, in the above general formula (1) or (2), 0≦x<0.1 and RE1 and RE2 are at least one element selected from the group of rare earth elements.
(FR)
L'invention concerne un rotor de Faraday, un isolateur optique et un équipement de traitement optique ayant une transmissivité supérieure à TGG, pouvant être réalisé à plus grande échelle et ayant un indice de performance élevé à une longueur d'onde dans la région des longueurs d'ondes du visible, en particulier 400 nm ou moins. Le rotor de Faraday est caractérisé en ce qu'il comprend comme composant principal un composé de fluorure représenté par la formule générale suivante (1) ou (2): RE1F3-x ・・・(1) LiRE2F4-x・・・(2) où, dans la formule générale ci-dessus (1) ou (2), 0≦x<0,1 et RE1 et RE2 sont au moins un élément sélectionné parmi le groupe des éléments des terres rares.
