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
