摘要：

Firstly, the analytical expression for the M-2 factor of the off-axial Hermite-cosh-Gaussian beams is derived based on the second-order moments definition. Secondly, the analytical propagation expression for the kurtosis parameter of the off-axial Hermite-cosh-Gaussian beams is also derived on the basis of the analytical propagation equation of the off-axial Hermite-cosh-Gaussian beams. It should be pointed out that the obtained results could be straightforwardly applied to the two-dimensional case and the off-axial Hermite-cosine-Gaussian beams.
