Paper Abstract

A series of optical ceramics based on dysprosium oxide were produced and characterized. The influence of ceramics composition on optical transmission of the obtained samples was investigated. The temperature dependences of the Verdet constant of dysprosium based ceramics with various compositions: (Dy0.7Y0.25La0.05 )2O3, (Dy0.85 Y0.1La0.05)2O3 and (Dy0.9Y0.05La0.05)2O3 in the temperature range 80 – 294 K and in the wavelength range 405 – 1064 nm were studied and their approximations for the temperature – wavelength range are obtained. Cryogenic cooling by the liquid nitrogen leads to increase studied ceramics’ Verdet constant value in ~3.46 times, relatively 294 K, that allow to use this material, in cryogenically cooled Faraday isolators for Tm3+ and Ho3+ lasers, and for lasers operating in the visible spectral region.
