摘要
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 important concepts relating to the flattened Gaussian beams(FGBs), such as the field distribution and beam width, are analyzed physically. The two dimensional(2D) FGB is extended to the three dimensional(3D) case, and the 3D symmetrical transformations, including equal beam widths in x and y dimensions and equal curvature radii at a z plane, are studied in detail.
