Abstract
Abstract Sodium terbium tungstate (NaTb(WO4)2) single crystal with dimension ∅ 25 mm×30 mm and a good optical quality was grown by Czochralski method. The transmission spectrum was measured in the visible and near-infrared region at room temperature. The specific Faraday rotation of single crystal was measured at room temperature in 532, 633, and 1064 nm wavelength. The Verdet constant and magneto-optical figure of merit was investigated. Comparing to the magneto-optical figure of merit and Verdet constant for TGG, the NaTb(WO4)2 have larger magneto-optical figure of merit and larger Verdet constant. It indicates that NaTb(WO4)2 crystal can be a promising magneto-optical material in visible region.
