Abstract
Second-harmonic generation (SHG) was observed in silicate glass contai ning Ga2O3 after electrical poling treatment. The SHG intensity was st rongest at the poling temperature of 250 degrees C and for the glass c ompoition of 7.5Li(2)O . 7.5Cs(2)O . 25Ga(2)O(3) . 60SiO(2) (mol%). Th e second-order nonlinear coefficient d(33) was as large as similar to 13% of d(22) for LiNbO3.
