摘要
为了进一步研究贝塞耳光束,贝塞耳-高斯光束的衍射特性,本文应用标量衍射理论,分别计算了4类典型光束,即平面波、高斯光束、贝塞耳光束和贝塞耳-高斯光束,通过圆孔硬边光阑后的轴向和横向光强分布。通过与熟知的平面波和高斯光束的衍射场分布进行比较分析,总结了贝塞耳光束,贝塞耳-高斯光束通过光阑后的衍射传播特点。
In order to further study the diffraction properties of a Bessel beam and Bessel - Gaussian beam, the scalar diffraction theory is employed in this paper to calculate the axial and transverse intensity distributions of the plane wave, Ganssian beam, Bessel and Bessel - Gaussian beam, respectively, when they propagate through a circular aperture. The properties of diffractive propagation of the Bessel and Bessel - Ganssian beams are summarized by comparing the diffractive field distributions of the well known plane wave and Ganssian beam.
