摘　　要：A beam deflector was designed and fabricated by using a lead lanthanum zirconate titanate （PLZT） ceramic with high quadratic electro-optic （EO） effect, based on refraction at an interface between areas with and without applied voltage. Its EO coefficients of R33 = 2.1×10^-16 V^2/m^2 and R13 = -0.37×10^-16 V^2/m^2 were obtained. Moreover, the hysteresis characteristics of the EO deflection were observed, and the effects of temperature on the characteristics of beam deflector were also investigated in detail.A beam deflector was designed and fabricated by using a lead lanthanum zirconate titanate （PLZT） ceramic with high quadratic electro-optic （EO） effect, based on refraction at an interface between areas with and without applied voltage.
