摘　　要：本文对应用于单次相关仪中的非线性晶体KDP的相位匹配条件进行了理论分析,得到了晶体的最佳相位匹配设计参数。利用此参数加工的非线性晶体已成功地用于测量超短光脉冲实验中,测得CPM Nd:YAG激光器输出的1.06μm光脉冲宽度为14ps.与条纹相机测量的结果二者符合较好。A analysis of phase matching conditions of nonlinear crystal KD P in single-shot, autocorrelator is presented in this paper. The optimum parameters of the crystal have been given. The nonlinear-crystal designed with the parameters has been successfully applied for measurement experiment of ultrashort optical pulse. CPM Nd:YAG laser output pulse duration of 14ps has been got for 1.06μm The experimental results are in keeping with the results of picosecond streak camera.
