FLATTENED GAUSSIAN BEAMS AND THEIR SYMMETRICAL TRANSFORMATIONS |
| |
Abstract: | 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. |

Keywords: | flattened Gaussian beam(FGB) beam width symmetrical transformation |
