标题： Experimental realization of vortex and vectorial vortex Pearcey-Gauss Beams

摘要： 在本手稿中，我们提出了两种新型的结构光束，具有均匀极化分布的涡旋 Pearcey-Gauss (VPeG) 束，以及具有非均匀极化分布的矢量涡旋 Pearcey-Gauss (VVPeG) 束。后者作为空间和极化自由度的不可分离叠加生成。我们还通过空间光调制器和 q-板的组合实现了它们的实验实现，其中空间光调制器生成标量 Pearcey-Gauss 束，而 q-板根据其输入极化状态将其转换为涡旋或矢量涡旋束。它们的强度和极化分布通过沿传播方向的 Stokes 偏振测量进行分析，并与数值模拟进行了比较。如所展示的，VVPeG 束从纯矢量束演化为准均匀极化分布的矢量模式。所提出的矢量束增加了现有的不可分离光态的丰富家族。我们预期这两种束将在光学计量、光学通信和光学镊子等多个领域找到应用。 显示英文摘要

摘要： In this manuscript, we put forward two new types of structured light beams, the vortex Pearcey-Gauss (VPeG) beam, with a homogeneous polarisation distribution, and the vector vortex Pearcey-Gauss (VVPeG) beam, with a non-homogeneous polarisation distribution. The later generated as a non-separable superposition of the spatial and polarisation degrees of freedom. We also achieve their experimental realization through the combination of a spatial light modulator, which creates a scalar Pearcey-Gauss beam, and a q-plate which transforms it into a vortex or a vortex vector beam, depending on its input polarisation state. Their intensity and polarisation distribution was performed through Stokes polarimetry, along the propagation direction, which was compared with numerical simulations. As demonstrated, the VVPeG beam evolves from a pure vector beam into a vector mode of quasi-homogeneous polarisation distribution. The proposed vector beams add to the already extensive family of non-separable states of light. We anticipate that both types of beams will find applications in fields as diverse as optical metrology, optical communications, and optical tweezers, amongst others.
