摘要
在柱坐标下从微分波动方程推导柱面光波和高斯球面波的场分布,并利用远场近似条件导出在垂直光轴方向的参考面上这两种光波的复振幅表示。
The field distributions of cylindrical wave fields and Gaussian beam fields are deduced from the wave differential equation in circular cylindrical coordinates. The expression of complex amplitude in reference plane vertical to the optical axis is derived by use of farfield approximation.
