The effect of spherically aberrated lens on the kurtosis parameter of Hermite-cosh-Gaussian beams
Abstract:The propagation of the K parameter of Hermite-cosh-Gaussian (HChG) beams passing through a spherically aberrated lens is studied by the straightforward integral of the Collins formula. Numerical calculations are made and the results show that for this case the K parameter changes upon propagation, and regardless of positive or negative aberration, spherical aberrations lead to an increment of the K parameter in comparison with the aberration-free case. The propagation properties of the K parameter of cosh-Gaussian (ChG) beams, and Hermite-Gaussian (H-G) beams are treated as special cases of HChG beams.
