摘　　要：　详细讨论了入射基频光的振幅调制和位相扰动对三倍频转换效率和动态范围的影响,提出了提高三倍频转换效率和增大动态范围的方法。采用I/II类角度失谐的KDP晶体三倍频方案,对倍频晶体的参数进行了优化设计。Effect of amplitude modulation and phase perturbation of incident fundamental field on the tripling efficiency and dynamic range has been discussed in details. The method which can improve the tripling efficiency and dynamic range has been proposed. Using type I/II angledetuning scheme for third harmonic generation, the parameter of harmonic conversion crystal has been optimized. 
