| 摘 要： | 引入了矢量非傍轴厄米余弦高斯(HCosG)光束的概念,从矢量瑞利 - 索末菲衍射积分公式出发,得出了矢量非傍轴HCosG光束在自由空间的解析传输公式,并将非傍轴HCosG光束在自由空间衍射时轴上、近场、远场以及在傍轴条件下的传输作为特例给出.数值计算和分析表明,对于矢量非傍轴HCosG光束,参数和偏心参数均对光束的非傍轴特性有重要影响.此外,其轴上光强分布与光束的阶数及其奇偶性有关.

| Abstract: | The concept of vectorial nonparaxial Hermite-cosine-Ganssian (HCosG) beams is introduced and their free space propagation equations are derived analytically by using the vectorial Rayleigh-Sommerfeld diffraction integrals and the on-axis and far-feld expressions as well as paraxial propagation formula are obtained in free space.Numerical calculations and analysis show that,the f-parameter and decentered parameter play important roles in determining the nonparaxiality of vectorial HCosG beams.In addition, th... |
