We report the Terahertz optical properties of the Vanadium doped [100] \beta-Ga2O3 using Terahertz Time-Domain Spectroscopy (THz-TDS). The V-doped \beta-Ga2O3 crystal shows strong birefringence in the 0.2-2.4 THz range. Further, phase retardation by the V-doped \beta-Ga2O3 has been measured over the whole THz range by Terahertz Time-Domain Polarimetry (THz-TDP). It is observed that the V-doped \beta-Ga2O3 crystal behaves both as a quarter waveplate (QWP) at 0.38, 1.08, 1.71, 2.28 THz, and a half waveplate (HWP) at 0.74 and 1.94 THz, respectively.
