Abstract

Based on the non-paraxial vectorial moment theory of light beam propagation and waveguide mode theory, the beam parameters of single-mode fiber including mode-field radius, divergence half-angle and beam propagation factor are analyzed and calculated. Especially, the results of beam propagation factor show that if both the core and cladding layer fields are considered, M²>1 is always obtained and neglect of the cladding layer field will lead to M²<1. These conclusions may be useful for further research on beam quality of fiber laser beam.
