摘要

近年来，二次径向依赖的轴对称贝塞尔调制高斯光束(QBG光束)受到了广泛的关注。本文利用矢量衍射理论，对径向偏振光位相波前径向变化的QBG光束的焦移进行了理论研究。波前相位分布是径向坐标的余弦函数。仿真结果表明，采用较小的光束参数可以有效地调节径向偏振QBG光束在焦点区域的强度分布

Generation of Tunable Focal Spot and Focal hole by Radially Polarized Axisymmetric Bessel-modulated Gaussian beam

In recent years, an Axisymmetric Bessel-modulated Gaussian beam with quadratic radial dependence (QBG beam) has attracted very much. In this paper, Focal shift in radially polarized QBG beam with radial variance phase wavefront is investigated theoretically byvector diffraction theory. The wavefront phase distribution is cosine function of radial coordinate. Simulation results show that the intensity distribution in focal region of the radially polarized QBG beam can be adjusted considerably by small beam parameter
