| 摘 要： | Based on the vectorial Rayleigh-Sommerfeld integral formulae,this paper derives the analytical nonparaxial propagation equation of a super-Lorentz-Gauss (SLG) SLG 01 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 SLG 01 mode beam are illustrated and analysed with numerical examples.This research provides an approach to investigate the propagation of the SLG 01 mode beam within the framework of the nonparaxial regime.
