在含Ga_2O_3的硅酸盐玻璃中观察到经电极化处理后的二次谐波产生。当极化温度为250° C，玻璃组成为7.5Li_2O·7.5Cs_2O·25Ga_2O_3·60SiO_2（mol%）时，倍频强度最强。二阶非线性系数d33为LiNbO3的d22的13%。
Second-harmonic generation (SHG) was observed in silicate glass containing Ga2O3 after electrical poling treatment. The SHG intensity was strongest at the poling temperature of 250° C and for the glass compoition of 7.5Li2O·7.5Cs2O·25Ga2O3·60SiO2 (mol%). The second-order nonlinear coefficient d33 was as large as ∼13% of d22 for LiNbO3.
