We propose and demonstrate a global and efficient approach for scalar and vectorial beam shaping based on the interaction of circularly polarized light with a single piece of homogeneous anisotropic medium. The main idea is to mimic the behavior of a two-dimensional inhomogeneous birefringent medium with a radial distribution of its optical axis. This is done by transforming an incident Gaussian beam into a conical nipple of light that further propagates along the optical axis of a c-cut uniaxial crystal.
我们提出并演示了一种基于圆偏振光与单块各向同性非均匀介质相互作用的标量和矢量光束整形的全局高效方法。其主要思想是通过将入射高斯光束变换成锥形光乳头来模拟二维非均匀双折射介质的行为，该锥形光乳头进一步沿着 c 切单轴晶体的光轴传播。
