| 摘 要： | 用恰克拉斯基（Ｃｚｏｃｈｒａｌｓｋｉ）法特殊工艺生长出尺寸为Φ３０×３０ｍｍ的优质Ｌｉ２Ｂ４Ｏ７单晶，讨论了工艺参数对晶体宏观缺陷的影响。用Ｍａｋｅｒ条纹测量了晶体的二次谐波系数ｄ３１和ｄ３３，结果表明，Ｌｉ２Ｂ４Ｏ７的ｄ３３是石英晶体ｄ１１的三倍。

Li2B4O7Single Crystal Growth and Second Harmonic Generation Coefficients |
| |
| Abstract: | The czochralski method was adoped to produced high optical quality Li2B4O7 single crystal with dimension of Φ30×30 mm through a special technique. Effects of technical parameters on the macrodefects of the single crystal were studied. Second harmonic generation (SHG) was studied by the Maker fringe method. The SHG coefficient d33 is three times higher than the d11 of quartz. |
