摘要
基于矢量瑞利-索末菲衍射积分,推导出矢量非傍轴双曲正弦-高斯光束在自由空间传输的解析公式,其远场的解析式作为一般传输公式的特例给出。利用所得结果通过数值计算方法分析了矢量非傍轴双曲正弦-高斯光束的传输特性。研究表明,双曲正弦-高斯光束的横向光强分布与偏心参数和传输距离有关。
Based on the vectorial Rayleigh-Sommerfeld diffraction integrals, the analytical expressions of vecto- rial nonparaxial sinh-Gaussian beams in free space are derived. As special cases of the general formulae, the far- field expressions of vectorial nonparaxial sinh-Gaussian beams is also given. According to the obtained analytical expressions, the propagation properties are illustrated and analyzed with numerical exampled. It is found that the transverse intensity distribution depends not only on the decentered parameter,？ but also on the distance.
