【摘要】 使用水热法成功生长出大尺寸、高质量的KTP晶体,对该晶体的光学性能进行测量分析。由LambDA900分光光度计测量得到的水热法生长KTP晶体的透过率曲线表明晶体具有良好的光透过性能,其透过短波下限与熔盐法生长的KTP晶体基本相当。利用自准直法精确测量水热法生长KTP晶体的折射率,拟合得到30℃下折射率的Sellmeier方程的系数,并计算532nm与1319nm波长对应的主轴折射率,计算值与实验值相吻合。更多还原

【Abstract】 The big and excellent KTP(KTiOPO4) crystals were successfull grown by hydrothermal method,and their optical character was measured.The transmission profile got by LambDA900 spectrophotometer shows that the KTP crystal has a good ability of transmission(between 453-2740nm,T>8%),and its cut-off shortwave is correspond with that of KTP grown by flux.By the auto-collimation method,the precise principle refractive indices of the hydrothermal KTP crystals were measured.Then,the coefficients of these Sellmeir-equations have been obtained base on the experimental data,and the principle refractive indices were calculated,those are fit with the measured ones.更多还原
