We derive solutions for radially polarized Bessel-Gauss beams in free-space by superimposing decentered Gaussian beams with differing polarization states. We numerically show that the analytical result is applicable even for large semi-aperture angles, and we experimentally confirm the analytical expression by employing a fiber-based mode-converter.
我们通过叠加具有不同偏振态的偏心高斯光束，推导出了自由空间中径向偏振贝塞尔 - 高斯光束的解。我们通过数值计算表明，该解析结果即使对于大的半孔径角也适用，并且我们通过使用基于光纤的模式转换器进行实验证实了该解析表达式。
