| Abstract: | A bundle of Ganssian beams passing through a circular aperture is focused by a lens. A study is deveted to the effect of its aperture-lens separation on its on-axis light distribution and its optimal focusing.The theoretical results show that there have been a close relation between light distribution of the focusedfield and the aperture-lens seperation. |

| Keywords: | Gaussian beam aperture-lens separation focusing |
