Characteristics of a PLZT electro optical deflector

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/m2 and R13=-0.37*10^(
