根据Sellmeier方程，利用计算机模拟对CLBO （CsLiB6O10）倍频的非线性光学特性进行了详细的理论研究，并与BBO在I型和II型相位匹配（PM）中的非线性光学特性进行了比较。我们获得了CLBO相对于BBO具有大的接受角和小的有效非线性系数的优点。根据本文导出的第一类和第二类公式，绘制了有效非线性系数、相位匹配角、偏离角、允许角和波长与基波长的关系曲线，以及SHG转换效率与晶体长度的关系曲线。对实验带在CLBO中的应用提出了理论指导。
According to Sellmeier equation, the detailed theoretical study using a computer stimulation on the nonlinear optical properties of CLBO (CsLiB6O10) frequency doubling are presented as compared to that of BBO in type I and type II phase matching (PM). We obtained the advantage of both a large acceptance angle and a small effective nonlinear coefficient of CLBO versus BBO. The curves of the effective nonlinear coefficient, phase matching angle, walk- off angle, permitted angle and wavelength versus the fundamental wavelength and SHG conversion efficiency versus the crystal length are plotted according to the formulas we derived in type I and type II from the PM. The theoretical guiding to experiments band application in CLBO is presented.
