  文中还利用fresnel数对两种传输过程的关系和聚焦光束的传输特性作了分析。
• 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
