On the basis of the second-order moment, the beam propagation of a higher-order cosh-Gaussian beam has been investigated. Two analytical expressions of the M 2 factor have been derived, which corresponds to the parity of the beam order n. The M 2 factor is determined by the beam order n and the para
Based on the non-paraxial vectorial moment theory of beam propagation, the analytical expressions of the M 2 factors for a non-paraxial hollow Gaussian beam (HGB) have been derived. The analytical formulae are further simplified for paraxial and highly non-paraxial cases. The beam waists, the diverg
