Research Abstract

The glasses have been believed optically isotropic and should not generate second harmonic wave. Recently, it has been found that second harmonic generation has been observed from SiO_2 glass after the thermal poling. We found that the second harmonic generation intensity of SiO_2 glasses prepared by various techniques depended on the OH concentration in the glasses, and SiO_2 glasses with high concentration of OH such as sol-gel derived SiO_2 glasses showed very strong second harmonic generation.
We also found that the addition of the TiO_2 caused second harmonic generation. From the research of the structure by, for instance, extened X-ray absorption fine structure, the intensity of second harmonic generation depended on Ti^<4+> in five-fold cordination of pyramid structure. Similarly, the addition of Ga_2O_3 or PbO caused second harmonic generation. In the case of PbO-SiO_2 glass, the intensity maximum appeard near 50mol% PbO,and the further increase of PbO content reduced the intensity. From the viewpoint of the chemical bond nature, the covalency of Pb-O bond increases from 50mol% PbO from the literature, and thus the chemical bond nature seems to affect the intensity of second harmonic generation.
