| Abstract: | A new kind of laser beam named off-axis elliptical flat-topped beam is proposed. This beam is expressed as a finite series
of off-axis elliptical Gaussian beams with different beam parameters. Analytical propagation formulas for the off-axis elliptical
flat-topped beam through aligned and misaligned optical systems are derived. As a numerical example, the propagation properties
of the off-axis elliptical flat-topped beam in free space are calculated and discussed. |
