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)V2/m~2 and R_(13)=-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.
