| Abstract: | With an approximate analysis, we study the focus qualities of the H-G beams which passing through a paraxial ABCD optical system with hard-edge aperture: focal shift and focal switch.It is shown that the results obtained by the approximate analysis have better consistences than by straightforward integral of the Collins formula and the working speed is highly improved. |
