Optical transmission, refractive-index, and nonlinear optical properties of single domain PbTiO3 have been measured between room temperature and the Curie temperature Tc. The second-harmonic coefficient d31 is found to be the highest for any room-temperature ferroelectric. Since the birefringence is small (approximately 0.008), phase-matched SHG is not possible, but nondegenerate three-frequency mixing should be possible. The Miller δ coefficients are analyzed in terms of Jerphagnon's formulation and poor agreement is observed.
