本文利用晶体球中非相位匹配二次谐波产生测量晶体二阶非线性系数的理论分析和实验结果。用 35皮秒脉冲光源泵浦的非相位匹配二次谐波转换效率可达 12 % ,测得的LiNbO3 晶体非线性系数d3 1=- 6 .48± 0 6 pmV-1,d2 2 =2 .2 6± 0 .3pmV-1。
In this paper, the theoretical analysis and experimental results of the second-order non-linear coefficient of the crystal produced by the non-phase-matching second harmonic in the crystal sphere are used. The non-phase-matching second harmonic conversion efficiency of up to 12% can be achieved with 35 picosecond pulsed light source. The measured nonlinear coefficients of LiNbO3 crystal d3 1 = -6.68 ± 0.6 pmV-1 and d2 2 = 2. 2 6 ± 0 .3 pmV-1.
