论文摘要
我们报告了一种基于自由空间多通单元的非线性材料相匹配的新方法。这个概念的准阶段与结晶石英相匹配，并将第二个谐波产生效率提高了40。
We report a new approach to phase matching of nonlinear materials based on the free space multipass cells. This concept quasi-phase matches crystalline quartz and increases the second harmonic generation efficiency by a factor 40.
