摘要
本文讨论了常用双轴晶体ＫＴＰ、ＬＢＯ、ＫＮ在基频光波长连续调谐时的倍频相位匹配特性，给出了这三种晶体在不同波长倍频时的最佳相位匹配角和有效倍频极化系数。
The phase matching characteristics of the second harmonic generation in biaxial crystals KTP,LBO and KN are discussed when the wavelengthes of the basic frequency lights turn continually.The optimum phase matching angles and the effective nonlinear susceptibility of the second harmonic generation with different wavelengthes in three crystals are given.And the erroneous calculating methods used ago are corrected.
