报道了35 ps激光脉冲射入直径为10 mm KTP晶体球的第Ⅰ类相位匹配二次谐波产生实验，根据二次谐波产生转换效率直接测量了KTP晶体的第Ⅰ类相位匹配曲线及相应的有效非线性系数，并与6组色散方程给出的理论匹配曲线比较，指出Vanherzeele的公式优于其他五组。

Phase-matched type Ⅰ second-harmonic generation in a 10 mm KTP crystal sphere using a 35 picosecond pulse as pump laser is reported. The type Ⅰ phase-matching (PM)curve of KTP crystal is measured directly according to the SHG conversion efficiency, and the corresponding nonlinear optical coefficient is calculated. By comparison of the experimental PM curve with the theoretical PM curves calculated from six Sellmeier’s equations, it is found that the equation given by Vanherzeele is the best one.
