Transformation properties of super-Gaussian beams passing through an astigmatic lens

Based on the generalized Huygens-Fresnel diffraction integral and the effect introduced by astigmatism,the transformation properties of super- Gaussian beams passing an astigmatic lens are studied numerically,and some important results are obtained.The beam quality of astigmatic super Gaussian beams is analyzed in terms of power in the bucket,and illustrated with numerical examples.
