摘要：

Light beams with elliptical flat-topped profiles are proposed. Such a beam can be expressed as a finite series of elliptical Gaussian beams with different parameters. Analytical propagation formulae for elliptical flat-topped beams passing through aligned and misaligned optical systems are derived. The fractional Fourier transform of the elliptical flat-topped beam is also studied. Our method provides a convenient way to describe the elliptical flat-topped beam and treat its propagation and transformation.
