The optical constants of YVO<inf>4</inf>crystal in the frequency range of 0.2 to 1.0 THz were determined using terahertz time-domain spectroscopy. The extraordinary-ray refractive indices varied from 4.05 to 4.07 and the ordinary-ray refractive indices were approximately 3.07. We found that YVO<inf>4</inf>crystal had a large and nearly constant birefringence of {\sim}0.985. In addition, the power absorptions for YVO<inf>4</inf>were less than 7 cm<sup>-1</sup>. Our results indicated that YVO<inf>4</inf>crystal has a potential for applications in the THz frequency range.
