论文摘要
我们研究了阈值低于阈值的I型光学参数振荡器（OPO）生成的频率梳子的横向模式效应。我们将衍射效果完全考虑到了通常的OPO架构，而不是自我成像设计。此外，我们表明，用结构化光泵送的OPO同时产生多个频率梳，对应于下频场中空间模式的不同组合。该结果可能适用于单个OPO的时空模式中杂交多部分纠缠的产生。
We investigate the transverse mode effects on the frequency combs generated by a type-I optical parametric oscillator (OPO) below threshold. We take the diffraction effects fully into account, considering usual OPO architectures instead of the self-imaging design. Further, we show that an OPO pumped with structured light produces multiple frequency combs simultaneously, corresponding to different combinations of spatial modes in the downconverted fields. This result may apply to the production of hybrid multipartite entanglement in the spatiotemporal modes of a single OPO.
