The study of the thermo-optical properties of a unique terbium oxide crystal was conducted. The key piezo-optical anisotropy parameter, ξ, which determines the prospects for using the material in isolators with high average power (more than 1 kW), was measured. It has been shown that the record-high value of the Verdet constant and the newly revealed negative value of ξ, equal to −0.11, make Tb 2 O 3 single crystals highly promising for use in high-power Faraday isolators.
