AbstractBy means of Collins diffraction integral formula in the paraxial approximation ,the analytical expression for azimuthally polarized Bessel-Gauss beam through any axisymmetric optical system that can be described by an ABCD ray transfer matrix is given in this paper. Free space propagation and Fourier transfer system are also analyzed and discussed as particular cases.
