Abstract

The azimuthal angle dependent transmittance in 0.2-2.2 THz frequency region for magnesium fluoride (MgF₂) crystal is measured by using a polarization sensitive detection method. The birefringence, absorption coefficient and refractive index have been studied. Based on the theory of crystal optics, the possibility of using magnesium fluoride (MgF₂) crystal as a THz wave plate is investigated. The coincidence of experimental data and theoretical curve demonstrates that these optical properties are sufficient for being used as wave plate operating in 0.2-2.2 THz frequency region.
