Abstract
Highly transparent ceramics of La‐doped 0.75Pb(Mg1/3Nb2/3)O3–0.25PbTiO3 were fabricated by a two‐stage sintering method from conventional raw materials. The ceramics exhibited a transparency as high as 65% for the infrared wavelength. Large quadratic electro‐optic coefficient of 66 × 10−16 (m/v)2 was obtained, which was the highest value reported so far in Pb(Mg1/3Nb2/3)O3–PbTiO3 ceramics. The ferroelectric phase inducing the threshold electric field Eth and the domain structure of the transparent ceramics were studied.
