Li2B4O7晶体生长及其二次谐波系数
Li2B4O7Single Crystal Growth and Second Harmonic Generation Coefficients
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。
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.
