Abstract: The authors have observed strain-induced second harmonic generation (SHG) signals from a Co0.25Pd0.75 alloy film deposited on a lead zirconate titanate (PZT) substrate. The strain in the sample was controlled by the inverse piezoelectric effect. The authors demonstrate that it is possible to separate the strain contribution to the SHG signal from the crystallographic contribution and that from the electric polarization in PZT. An estimate of the value of the nonlinear photoelastic tensor components is in very good agreement with previous calculations. (c) 2007 American Institute of Physics.
