摘　　要：从理论和实验两方面对径向振无衍射束进行了研究.理论上数值模拟了径向振无衍射束传输特性.模拟结果表明,径向振无衍射光束既具有径向振特性又具有无衍射特性.实验上我们利用高斯束经过径向振转换器后由轴棱锥聚焦获了径向振无衍射束,并使其经过不同角度振后到同振方向上强分,实验结果与理论结果一致.这种既具有径向振特性又具有无衍射特性束具有阔应用前景.In this paper, we theoretically and experimentally investigate the properties of radially polarized non-diffracting beam The propagation properties of the radially polarized non-diffracting beam are theoretically simulated. It is shown that the radially polarized non-diffracting beams possess both the radial polarization and non-diffracting characteristics. The radially polarized non-diffracting beam is experimentally generated by a Gaussian beam passing through a radial polarization converter and then focused by an axicon. The dependence of the intensity distribution of radially polarized non-diffracting beam on the polarization angle of the polarizer is experimentally observed, showing good agreement with the theoretical results. The beams with both the radial polarization and non-diffracting properties have many important potential applications.
