| 摘 要： | Based on the vectorial Rayleigh--Sommerfeld integral
formulae, this paper derives the analytical nonparaxial propagation
equation of a super-Lorentz--Gauss (SLG) SLG01 mode beam in
free space. The far field expression and the scalar paraxial result
are treated with special cases of the general formulae.
According to the obtained analytical representation, the nonparaxial
propagation properties of the SLG01 mode beam are illustrated
and analysed with numerical examples. This research provides an
approach to investigate the propagation of the SLG01 mode beam
within the framework of the nonparaxial regime.
