The propagation and focusing properties of partially coherent vector beams including radially polarized and azimuthally polarized (AP) beams are theoretically and experimentally investigated. The beam profile of a partially coherent radially or AP beam can be shaped by adjusting the initial spatial coherence length. The dark hollow, flat-topped, and Gaussian beam spots can be obtained, which will be useful in trapping particles. The experimental observations are consistent with the theoretical results.
对包括径向偏振和角向偏振（AP）光束在内的部分相干矢量光束的传输和聚焦特性进行了理论和实验研究。通过调整初始空间相干长度，可以对部分相干径向或AP光束的光束轮廓进行整形。可以获得暗空心、平顶和高斯光束光斑，这在捕获粒子方面将很有用。实验观测结果与理论结果一致。
