摘要
推导出基模高斯光束经圆波片后的近轴光场分布的一般解析表达式 ,讨论该衍射场在不同情况下的传播特性 ,并对衍射场分布的近轴解析解给出相应的物理解释。
The general analytical expression of paraxial optical field contribution of base mode Gaussian beam passing through a circular phase-plate is derived in this paper.The propagation characteristic of this diffraction field is discussed in varying cases.The corresponding physical interpretation of paraxial analytical solution for this diffraction field is given.
