Paper Abstract

The Verdet constant dispersion of CeF 3 crystal was measured in the spectral range from 0.45 to 1.95    μ m . To the best of our knowledge, CeF 3 crystal was investigated for the first time as a potential material candidate for near-infrared Faraday rotators (FRs). The experimental results obtained for Verdet constant dispersion were compared to other magneto-optical materials with the conclusion that CeF 3 crystal possesses up to 60% higher Verdet constant in the near-infrared spectral region 1.1 to 1.5    μ m compared to widely used terbium gallium garnet crystal. Furthermore, the presented experimental setup is capable of high precision measurement of Verdet constant dispersion in a broad spectral range, with measurement error not exceeding 5%, therefore, representing a powerful tool for FRs development.
