对平顶高斯光束有关的一些重要概念，例如场分布和束宽等作了物理分析。进一步将二维平顶高斯光束推广到三维情况，并且对三维平顶高斯光束的对称化变换，包括在ｘ和ｙ 方向束宽相等和 ｚ 平面处曲率半径相等，进行了详细的研究。
Some of the important concepts related to flattened Gaussian beams, such as field distribution and beamwidth, are analyzed physically. The two-dimensional flat-topped Gaussian beam is further extended to the three-dimensional case, and the symmetric transformation of the three-dimensional flattened Gaussian beam, including equal beamwidths in the x and y directions and equal curvature radii in the z plane, has been studied in detail.
