摘要:
基于Collins公式,导出角向偏振螺旋贝塞尔光束的光场表达式,研究该光束的传输特性及暗核位置对光束偏振态的影响.通过理论分析和数值计算发现:角向偏振螺旋贝塞尔光束在一定传输区域内是以空心光束绕光轴做离轴螺旋传输,并且光束的发散角为0;光束的偏振态随着暗核位置的移动而发生整体偏移.
Abstract:
Based on the Collins formula, the intensity expression of the azimuthally polarized spiral Bessel beam is deduced. The propagation properties of the beam and the influence of the position of the dark core on the polarization state of the beam have been investigated. It is found that, by the theoretical analysis and numerical calculation, in a certain transmission region, the azimuthally polarized spiral Bessel beam is an off-axis spiral transmission of the hollow beam around the optical axis, and the divergence angle of the beam is zero; the polarization state of the beam cause overall migration with the move of the dark core position.
