  1. It is shown that the fgb and sgb passing through a paraxial abcd system demonstrate similar irradiance profile at the positions of the equal generalized fresnel number. but the fgb and sgb passing through a paraxial abcd optical system having spherically aberrated lens do not demonstrate similar irradiance profile at the positions of the equal generalized fresnel number. the nearly same irradiance profile at the positions of the equal generalized fresnel number can be achieved if the fgb and sgb have the same a / 2 - factor and waist width
