Highly transparent ceramics of La‐doped 0.75Pb(Mg 1/3 Nb 2/3 )O 3 –0.25PbTiO 3 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(Mg 1/3 Nb 2/3 )O 3 –PbTiO 3 ceramics. The ferroelectric phase inducing the threshold electric field E th and the domain structure of the transparent ceramics were studied.
