| Abstract: | In this paper, Formulae for the focal spot size of gaussian Iaser beam with two-lens focusing system are derived by q (z) of gaussian beam .Using the two-lens focusing system, focal spot size of μmn or less was easily obtained, and longer working distance can be obtained than other focusing system. |
