The refractive indices and linear electro-optic properties of relaxor ferroelectric crystal 0.93Pb(Zn1/3Nb2/3)O3- 0.07PbTiO3 in the rhombohedral phase were investigated at room temperature using the 632.8 nm He-Ne laser. The two principal refractive indices were measured by the Brewster's angle method: no=2.466, ne=2.488. The linear electro-optic coefficients were determined using the modified Mach-Zehnder interferometer method to be r33=71 pm/V, r13=4 pm/V. The effective E-O coefficient and half-wave voltage were also calculated: rc=67 pm/V and Vπ=610 V. The excellent E-O properties show that the PZN-0.07PT single crystal has potential application in the field of laser modulation and deflection field.
