•TbVO4 crystals were grown by the Czochralski method under different growth atmosphere.•TV crystal grown at N2 + CO2 mixed atmosphere has high transmittance at 600–1500 nm waveband.•TbVO4 crystal has larger Verdet constants than those of TGG crystal.
TbVO4 (TV) single crystals with dimensions of 18 × 18 × 16 mm3 were grown by Czochralski method under different atmosphere. XPS studies revealed the presence of V4+ and Tb4+ in TV crystal grown at 99.9% N2 atmosphere, which caused a wide absorption peak centered at 950 nm in the transmission spectrum. TV crystal grown at 80% N2 + 20% CO2 mixed atmosphere has high transmittance at 600–1500 nm waveband. Faraday rotation spectra of TV crystal were measured. TV crystal has a larger Faraday rotation than terbium gallium garnet (TGG) crystal at 500–1500 nm waveband.
