Second Harmonic Generation from Electrically Poled PbO-SiO2 Glasses
1998
Journal of the Ceramic Society of Japan
Preserved Fulltext
Clear second harmonic generation (SHG) was observed from xPbO(100x)SiO2 glasses after electrical pol ing. PbO can be considered to be responsible for the SHG center since no SHG was detected from electrically poled PbO-free SiO2 glass. SHG was seen from the glasses poled above 100, and the intensity increased as the poling temperature increased. The minimum dc voltage necessary for SHG was 1kV. SHG intensity in creased first and then decreased with the increase of PbO content, showing a maximum
