摘要
报道了ＫＤＰ晶体中的三倍频产生的实验研究，计算并比较了直接三倍频过程和级联过程对ＫＤＰ晶体三阶有效非线性系数的贡献。
Third harmonic generation (THG) in KDP crystals was reported. Based on the experimental result, we analyzed and compared the contributions to KDP third order nonlinearity for direct THG process and cascading process. As a result, we discussed the possibility of using KDP as the standard in measuring the coefficient of nonlinear optical crystals.
