| dc.description | The second-harmonic generation (SHG) of nominally pure lead phosphate Pb<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub>, was reinvestigated. SHG is confirmed at room temperature albeit with a large spatial variation within each sample. The signal did not disappear when the crystal was heated well above the ferroelastic transition temperature of 453 K. Chemical analysis using X-ray microprobe techniques showed a weak oxygen deficit for all samples. It is suggested that SHG is not necessarily indicative of an intrinsic symmetry breaking process in Pb<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub> but may be related to structural imperfections. |
