摘　　要：本工作测试了 LBO 单晶的折射率、电光系数、光吸收谱、红外光谱和喇曼光谱,详细分析了 LBO 晶体的光谱及其相应的晶格振动情况.实验表明,透明的、未掺杂的 LBO 晶体没有观察到明显的光折变效应.The refractive indexes,electrooptical coefficients,transmission,infrared and Raman spec-tra of the new piezoelectric single crystal Li_2B_4O_7 grown by BR method were reported in thispaper.The spectra and its corresponding lattice vibration mode were discussed in detail.Noobvious photorefractive effect was observed in transparent and undoped Li_2B_4O_7 single crystal.
