双轴晶体中三波相互作用时的最佳相位匹配问题
The optimun phase matching (PM) of three wave interactions in biaxial crystals
摘要
本文论述了双轴晶体中和频、差频、参量振荡、参量放大等各种三波相互作用过程时相位匹配曲线及有效非线性系数的数值计算方法.从而只要知道某种双轴晶体对相应波长的主折射率及非线性系数后,便可求得最佳相位匹配角θ(OPM)和φ(OPM).本文报导了对六种双轴晶体的计算结果和对二种双轴晶体的实验情况.实验结果与计算结果十分一致.
Abstract
This paper discusses the calculation methods of the PM loci and the effective second-order nonlinear coefficients dIeff and dIIeff of three wave interactions, such as SF, DF, OPO and etc. in biaxial crystals. It is found that the optimum PM angles ?OPM and ?OPM can be calculated by computers. The paper also reports the computed results for 6 biaxial crystals and the experimental results for 2 biaxial crystals. The computed resulte agree quite favorably with the experimental results.
