我们报告了一个简洁而有效的实验，以扩展研究的完整庞加莱光束，将非线性光学效应。该方案的主要特点是采用II型相位匹配KTP晶体实现结构矢量光从可见光到不可见光的二次谐波产生。特别感兴趣的是隐藏的拓扑结构的启示和可视化从输入偏振态的输出可观察到的强度模式。实验结果与数值模拟结果吻合较好。我们目前的工作为我们提供了深入了解在非线性制度的完整庞加莱光束与介质的相互作用。
We report a concise yet efficient experiment to extend the study of full Poincaré beams to incorporate the nonlinear optical effect. The main feature of our scheme is the employment of Type-II phase-matching KTP crystal to implement the second harmonic generation with structured vector light from invisible to visible region. Of particular interest is the revelation and visualization of the hidden topological structures transferred from the input polarization state to the output observable intensity patterns. The experimental results are in good agreement with the numerical simulations. Our present work provides us with the insight into the interaction of full Poincaré beams with media in the nonlinear regime.
