Abstract
Although one expects second harmonic generation to be absent in phases with inversion symmetry, second harmonic signals are observed in the paraelectric phase of several perovskite. We explain this frequency-doubled intensity and its temperature dependence by second harmonic scattering (SHS) due to static point defects inducing a local polarisation and dynamic fluctuations. The intensity and polarisation properties are calculated for both contributions.
