In a recent publication (Appl. Phys. Lett. 100 (2012) 051108), a monochromatic partially coherent radially polarized (RP) beam was generated experimentally. In this paper, we analyze the spectral changes of a polychromatic partially coherent RP beam focused by a thin lens for the first time, and compare with that of a focused scalar polychromatic GSM beam. Furthermore, we report experimental generation of a polychromatic partially coherent RP beam and carry out experimental measurement of the spectral changes of such beam focused by a thin lens. Our results show that the behavior of the spectral changes of a focused polychromatic partially coherent RP beam is different from that of a focused scalar polychromatic GSM beam. Our experimental results are consistent with the theoretical predictions.
在最近的一篇出版物（《应用物理快报》100 (2012) 051108）中，通过实验产生了单色部分相干径向偏振（RP）光束。在本文中，我们首次分析了由薄透镜聚焦的多色部分相干RP光束的光谱变化，并与聚焦标量多色GSM光束的光谱变化进行比较。此外，我们报告了多色部分相干RP光束的实验产生，并对由薄透镜聚焦的此类光束的光谱变化进行了实验测量。我们的结果表明，聚焦多色部分相干RP光束的光谱变化行为与聚焦标量多色GSM光束的不同。我们的实验结果与理论预测一致。
