Besides, the crystal temperature influenced on experiment result was analyzed, and temperature matching condition of LBO was given out.
另外从理论上分析了晶体温度对实验结果的影响，推导出了LBO晶体的温度匹配条件。

One of the most effective and feasible ways of broadening the range of the output wavelength is using frequency conversion of non-linear Crystal under the condition of phase matching.
拓宽激光输出波长的范围最常用最有效的方法之一是利用非线性晶体在相位匹配条件下的频率变换技术。
