A second harmonic generation study of the ACuTe2O7 quasi-1D materials

Quasi-one-dimensional polar materials can potentially exhibit interesting properties such as pronounced non-linear optical responses like second harmonic generation and optical rectification. A comparative study of optical second harmonic generation from BaCuTe2O7, which is polar, and SrCuTe2O7, which is reportedly non-polar and centrosymmetric will be presented here. The relationship between the SHG magnitude and the onset of magnetic correlations in these compounds will also be shown.
